http://sciencewatch.com/dr/sci/10/jan17-10_3/ Five-year Wilkinson Microwave Anisotropy Probe observations: Likelihood and parameters from the WMAP data, by J. Dunkley and 18 others, Astrophysical Journal Supplement Series , 180(2): 306-29, February 2009. From the abstract: This paper focuses on cosmological constraints derived from analysis of WMAP data alone. A simple Lambda CDM cosmological model fits the five-year WMAP temperature and polarization data. The basic parameters of the model are consistent with the three-year data and now better constrained. With five years of polarization data, we have measured the optical depth to reionization, tau 0, at 5 sigma significance. The redshift of an instantaneous reionization is constrained to be z(reion) = 11.0 +/- 1.4 with 68% confidence. The 2 sigma lower limit is z(reion) 8.2, and the 3 sigma limit is z(reion) 6.7. This excludes a sudden reionization of the universe at z = 6 at more than 3.5 sigma significance, suggesting that reionization was an extended process. Using two methods for polarized foreground cleaning we get consistent estimates for the optical depth, indicating an error due to the foreground treatment of tau similar to 0.01. This cosmological model also fits small-scale cosmic microwave background (CMB) data, and a range of astronomical data measuring the expansion rate and clustering of matter in the universe. This 2009 report from Astrophysical Journal Supplement Series was cited 75 times in current journal articles indexed by Thomson Reuters during September-October 2009. With that latest two-month tally, this report is currently the second-most-cited physics paper published in the last two year, aside from reviews. (In fact, the paper is second only to another report on the Wilkinson Microwave Anisotropy Probe , from the same journal issue.) Prior to the most recent bimonthly count, citations to the paper have accrued as follows: July-August 2009: 51 citations May-June 2009: 54 March-April 2009: 19 January-February 2009: 4 Total Citations to date: 203

PHYSICS The Top Ten lists in Physics feature papers published during the last two years (excluding review articles) that were most cited in current journal articles indexed by Thomson Reuters during a recent two-month period. Papers are ranked according to the latest bimonthly citation count. The articles below are accompanied by expert discussion and analysis (including comments from the papers authors) written by one of four veteran scientist-journalists and longtime ScienceWatch.com contributors. 2009 November/December 2009 Strung-Out Theorists Put Their M2-Branes Together by Simon Mitton After an absence of a few months, recent papers on M2-branes return to the Physics Top Ten. M2-branes (the designation brane is derived from the word membrane) are part of the framework of string theory, an attempt to combine general relativity and quantum mechanics in an effort to find a quantum theory of gravity. Among other matters, the papers on M2 branes provide an algebraic framework by which theorists can test and advance these larger constructs. View Article September/October 2009 Five Years of WMAP : Still Answering Cosmic Questions by Simon Mitton The latest release of data from the Wilkinson Microwave Anisotropy Probe ( WMAP ), marking the fifth such annual publication of findings, continues to add to the spacecrafts impressive yield of knowledge pertaining to cold dark matter, dark energy, and other fundamental apects of cosmology. In particular, WMAP has contributed to the examination of how the universe inflated after the Big Bang, and whether or not the universe displays curvature. View Article July/August 2009 For Sloan Digital Sky Survey, Acclaim Across the Universe by Simon Mitton An assessment of the Sloan Digital Sky Survey (SDSS) reviews the projects many contributions to astronomy. The SDSS telescope and its imaging equipment have added immeasurably to knowledge of celestial objects and the development of the universe. As of now, more than 12,000 square degrees of the sky have been imaged, and untold numbers of galaxies and quasars fixed in the creation of three-dimensional maps. The project is expecting to continue yielding data until 2014. View Article May/June 2009 The Good Samarium Hots Up Superconductivity by Simon Mitton Research on iron-based superconductors continues to occupy the higher rungs among the most-cited papers in physics. One 2008 report examines the use of samarium in place of lanthanum in a superconducting compound, while other reports look at F doping and its effects. Transition temperatures in iron-based superconductors continue to edge up, moving toward the ultimate goal of achieving superconductivity at room temperature. View Article March/April 2009 Is This the Third Revolution for String Theory? by Simon Mitton String theory, the framework for understanding the fundamental forces in the universe, has resurged in recent years, particularly with refinements to so-called M-theory. A group of recent papers examine M2-branes, which are entities that fit into the multidimensional scheme of current string theory. The work has required the invention of a new algebra to help explain the dynamics of the system. In all, this new wave of papers appears to constitute a third revolution in string theory. View Article January/February 2009 Precision Cosmology Soars to New Heights by Simon Mitton Space science currently accounts for half of the most-cited papers in physics published over the last two years. These reports, in particular, reflect the progression of cosmologythe effort to understand the basic nature of the universefrom theory to a precise science grounded in solid numerical models. Current Hot Papers highlight recent findings on the makeup and characteristics of the universe based on the Wilkinson Microwave Anisotropy Probe, the Hubble Space Telescope, and the Sloan Digital Sky Survey. View Article 2008 November/December 2008 Extraordinary X-Ray Observatory Excites Astronomers by Simon Mitton Suzaku, the Japanese X-ray observatory launched in 2005, is producing highly cited papers and providing an international team of astronomers with abundant data on gamma-ray bursts, solar flares, supernovae, and other celestial phenomena.

The result is that these life-forms not only fail to interbreed, but can fail to find common ground even when placed in proximity on a university campus. And yet, the underlying intellectual DNA remains remarkably similar, in analogy to the findings of recent research in biology. The purpose of this present text is to identify common strands in the substrate of variational theory and to express them in a form that is intelligible to participants in these subfields. The goal is to make hard-won insights from each line of development accessible to others, across the barriers that separate these specialized intellectual niches. Another great revolutionwas initiated in the last midcentury, with the introduction of digital computers. In many subfields, there has been a fundamental change in the attitude of practicing theoreticians toward their theory, primarily a change of practical goals. There is no longer a well-defined barrier between theory for the sake of understanding and theory for the sake of predicting quantitative data. Given modern resources of computational power and the coevolving development of efficient algorithms and widely accessible computer program tools, a formal theoretical insight can often be exploited very rapidly, and verified by quantitative implications for experiment. A growing archive records experimental controversies that have been resolved by quantitative computational theory. It has been said that mathematics is queen of the sciences. The variational branch of mathematics is essential both for understanding and predicting the huge body of observed data in physics and chemistry. Variational principles and methods lie in the bedrock of theory as explanation, and theory as a quantitative computational tool. Quite simply, this is the mathematical foundation of quantum theory, and quantum theory is the foundation of all practical and empirical physics and chemistry, short of a unified theory of gravitation. With this in mind, the present text is subdivided into four parts. The first reviews the variational concepts and formalism that developed over a long history prior to the discovery of quantum mechanics, subdivided into chapters on history, on classical mechanics, and on applied mathematics (severely truncated out of respect for the vast literature already devoted to this subject). The second part covers variational formalism and methodology in subfields concerned with bound states in quantum mechanics. There are separate chapters on time-independent quantum mechanics, on independent-electron models, which may at some point be extended to independent-fermion models as the formalism of the Standard Model evolves, and on time-dependent theory and linear response. The third part develops the variational theory of continuum states, including chapters on multiple scattering theory (the essential formalism for electronic structure calculations in condensed matter), on scattering theory relevant to the true continuum state of a quantum target and an external fermion (with emphasis on methodology for electron scattering by atoms and molecules), continuing to a separate chapter on the currently developing theory of electron-impact rotational and vibrational excitation of molecules. The fourth part develops variational theory relevant to relativistic Lagrangian field theories. The single chapter in this part derives the nonquantized field theory that underlies the quantized theory of the current Standard Model of elementary particles. This book grew out of review articles in specialized subfields, published by the author over nearly fifty years, including a treatise on variational methods in electronatom scattering published in 1980. Currently relevant topics have been extracted and brought up to date. References that go more deeply into each of the topics treated here are included in the extensive bibliography. The purpose is to set out the common basis of variational formalism, then to open up channels for further exploration by any reader with specialized interests. The most recent source of this text is a course of lectures given at the Scuola Normale Superiore, Pisa, Italy in 1999. These lectures were presented under the present title, but concentrated on the material in Parts I and II here. The author is indebted to Professor Renato Colle, of Bologna and the Scuola Normale, for making arrangements that made these lectures possible, and to the Scuola Normale Superiore for sponsoring the lecture series.

These can be made visibily in a Ramsey type interference experiment. For a disentangled state (left) the visibility of the resulting Ramsey interference pattern is rather high, whereas for an entangled state (middle) the visibility almost vanishes. A further application of the quantum gates can however restore the interference pattern again (right).

They provide excellent shielding of quantum information from environmental noise, while strong, well-controlled laser interactions readily provide quantum logic gates. A number of basic quantum information protocols have been demonstrated with trapped ions. Much current work aims at the construction of large-scale ion-trap quantum computers using complex microfabricated trap arrays. Several groups are also actively pursuing quantum interfacing of trapped ions with photons. 17 pages The physics of 2 1 + 1 Yanhua SHIH (史砚华) Department of Physics, University of Maryland, Baltimore County, Baltimore, MD 21250, USA E-mail: shih@umbc.edu One of the most surprising consequences of quantum mechanics is the entanglement of two or more distant particles. In an entangled EPR two-particle system, the value of the momentum (position) for neither single subsystem is determined. However, if one of the subsystems is measured to have a certain momentum (position), the other subsystem is determined to have a unique corresponding value, despite the distance between them. The peculiar behavior of an entangled quantum system has surprisingly been observed experimentally in two-photon temporal and spatial correlation measurements, such as ghost interference and ghost imaging. This article addresses the fundamental concerns behind these experimental observations and to explore the nonclassical nature of two-photon superposition by emphasizing the physics of 21 + 1. 28 pages Generation and detection of infrared single photons and their applications He-ping ZENG (曾和平) 1* , Guang WU (吴光) 1 , E.

It is quantum physics that gives us hope to turn this wizardly dream into reality. The rapid development of quantum cryptography may put an end to the history of eavesdropping. This will be largely due to the advanced techniques related to single quanta, especially infrared single photons. In this paper, we report on our research works on single-photon control for quantum cryptography, ranging from singlephoton generation to single-photon detection and their applications. 20 pages Continuous variable quantum communication with bright entangled optical beams Chang-de XIE (谢常德) * , Jing ZHANG (张靖), Qing PAN ( 潘庆), Xiao-jun JIA (贾晓军), Kun-chi PENG (彭堃墀) State Key Laboratory of Quantum Optics and Quantum Optics Devices, Institute of Opto-Electronics, Shanxi University, Taiyuan 030006, China E-mail: changde@sxu.edu.cn In this paper, we briefly introduce the basic concepts and protocols of continuous variable quantum communication, and then summarize the experimental researches accomplished by our group in this field. 13 pages The security and recent technology of quantum key distribution Xiang-bin WANG (王向斌) 1* , Hao YIN (尹浩) 2 , Huai-xin MA (马怀新) 2 , Cheng-zhi PENG (彭承志) 1 , Tao YANG (杨涛) 3 , Jian-wei PAN (潘建伟) 3 1 Department of Physics, Tsinghua University, Beijing 100084, China 2 China Electronic System Engineering Company, Beijing 100039, China 3 Hefei National Laboratory for Physical Sciences at Microscale,University of Science and Technology of China, Hefei 230026, China E-mail: wang_xiangbin@hotmail.com In principle, quantum key distribution (QKD) can be used to make unconditionally secure private communication. However, the security of the existing real system for QKD needs to be carefully examined.
