Based on ab initio calculations of the light and plasmon fields we extract energy rates and ... Model Independent Analysis of Proton Structure for Hydrogenic Bound States [作者：Hill, RJ; Paz, G,期刊：PHYSICAL REVIEW LETTERS, 页码：160402-160402 , 文章类型： Article，,卷期：2011年107-16] Proton structure effects in hydrogenic bound states are analyzed using nonrelativistic QED effective field theory. Implications for the Lamb shift in muonic hydrogen are discussed. Model-dependent assumptions in previous... Chiral Scale and Conformal Invariance in 2D Quantum Field Theory [作者：Hofman, DM; Strominger, A,期刊：PHYSICAL REVIEW LETTERS, 页码：161601-161601 , 文章类型： Article，,卷期：2011年107-16] It is well known that a local, unitary Poincare-invariant 2D quantum field theory with a global scaling symmetry and a discrete non-negative spectrum of scaling dimensions necessarily has both a left and a right local co... Phase Transitions Detached from Stationary Points of the Energy Landscape [作者：Kastner, M; Mehta, D,期刊：PHYSICAL REVIEW LETTERS, 页码：160602-160602 , 文章类型： Article，,卷期：2011年107-16] The stationary points of the potential energy function V are studied for the phi(4) model on a two-dimensional square lattice with nearest-neighbor interactions. On the basis of analytical and numerical results, we explo...

The observed density depletion and open ma... Nonresonant Broadband Funneling of Light via Ultrasubwavelength Channels [作者：Subramania, G; Foteinopoulou, S; Brener, I,期刊：PHYSICAL REVIEW LETTERS, 页码：163902-163902 , 文章类型： Article，,卷期：2011年107-16] Enhancing and funneling light efficiently through deep subwavelength apertures is essential in harnessing light-matter interaction. Thus far, this has been accomplished resonantly, by exciting the structural surface plas... Leidenfrost Gas Ratchets Driven by Thermal Creep [作者：Wurger, A,期刊：PHYSICAL REVIEW LETTERS, 页码：164502-164502 , 文章类型： Article，,卷期：2011年107-16] We show that thermal creep is at the origin of the recently discovered Leidenfrost ratchet, where liquid droplets float on a vapor layer along a heated sawtooth surface and accelerate to velocities of up to 40 cm/s. As t... Objectively Discerning Autler-Townes Splitting from Electromagnetically Induced Transparency [作者：Anisimov, PM; Dowling, JP; Sanders, BC,期刊：PHYSICAL REVIEW LETTERS, 页码：163604-163604 , 文章类型： Article，,卷期：2011年107-16] Autler-Townes splitting (ATS) and electromagnetically induced transparency (EIT) both yield transparency in an absorption profile, but only EIT yields strong transparency for a weak pump field due to Fano interference. E... Analysis of Thomson Scattering from Nonequilibrium Plasmas [作者：Chapman, DA; Gericke, DO,期刊：PHYSICAL REVIEW LETTERS, 页码：165004-165004 , 文章类型： Article，,卷期：2011年107-16] We develop the theory for light scattering as a diagnostic method for plasmas in nonequilibrium states. We show how well-known nonequilibrium features, like beam acoustic modes, arise in the spectra. The analysis of an e... Partial Order and Finite-Temperature Phase Transitions in Potts Models on Irregular Lattices [作者：Chen, QN; Qin, MP; Chen, J; Wei, ZC; Zhao, HH; Normand, B; Xiang, T,期刊：PHYSICAL REVIEW LETTERS, 页码：165701-165701 , 文章类型： Article，,卷期：2011年107-16] We evaluate the thermodynamic properties of the 4-state antiferromagnetic Potts model on the Union-Jack lattice using tensor-based numerical methods. We present strong evidence for a previously unknown, "entropy-driven,"... Dynamic Nuclear Spin Resonance in n-GaAs [作者：Chen, YS; Reuter, D; Wieck, AD; Bacher, G,期刊：PHYSICAL REVIEW LETTERS, 页码：167601-167601 , 文章类型： Article，,卷期：2011年107-16] The dynamics of optically detected nuclear magnetic resonance is studied in n-GaAs via time-resolved Kerr rotation using an on-chip microcoil for rf field generation.
