Distributions of Waiting Times of Dynamic Single-Electron Emitters [作者：Albert, M; Flindt, C; Buttiker, M,期刊：PHYSICAL REVIEW LETTERS, 页码：86805-86805 , 文章类型： Article，,卷期：2011年107-8] The distribution of waiting times between elementary tunneling events is of fundamental importance for understanding the stochastic charge transfer processes in nanoscale conductors. Here we investigate the waiting time ... Comment on "Thermostatistics of Overdamped Motion of Interacting Particles" Reply [作者：Andrade, JS; da Silva, GFT; Moreira, AA; Nobre, FD; Curado, EMF,期刊：PHYSICAL REVIEW LETTERS, 页码：88902-88902 , 文章类型： Editorial Material，,卷期：2011年107-8] Unconventional Surface Impedance of a Normal-Metal Film Covering a Spin-Triplet Superconductor Due to Odd-Frequency Cooper Pairs [作者：Asano, Y; Golubov, AA; Fominov, YV; Tanaka, Y,期刊：PHYSICAL REVIEW LETTERS, 页码：87001-87001 , 文章类型： Article，,卷期：2011年107-8] We discuss the dynamic response of odd-frequency Cooper pairs to an electromagnetic field. By using the quasiclassical Green function method, we calculate the impedance (Z = R - iX) of a normal-metal thin film which cove... Transport and Accumulation of Spin Anisotropy [作者：Baumgartel, MME; Hell, M; Das, S; Wegewijs, MR,期刊：PHYSICAL REVIEW LETTERS, 页码：87202-87202 , 文章类型： Article，,卷期：2011年107-8] We show that spin anisotropy can be transferred to an isotropic system by transport of a spin-quadrupole moment. We derive the quadrupole moment current and continuity equation and study a spin-valve structure consisting... Perturbative Quantum Error Correction [作者：Beny, C,期刊：PHYSICAL REVIEW LETTERS, 页码：80501-80501 , 文章类型： Article，,卷期：2011年107-8] We derive simple necessary and sufficient conditions under which a quantum channel obtained from an arbitrary perturbation from the identity can be reversed on a given code to the lowest order in fidelity. We find the us... Simultaneous Quantization of Bulk Conduction and Valence States through Adsorption of Nonmagnetic Impurities on Bi(2)Se(3) [作者：Bianchi, M; Hatch, RC; Mi, JL; Iversen, BB; Hofmann, P,期刊：PHYSICAL REVIEW LETTERS, 页码：86802-86802 , 文章类型： Article，,卷期：2011年107-8] Exposing the (111) surface of the topological insulator Bi(2)Se(3) to carbon monoxide results in strong shifts of the features observed in angle-resolved photoemission. The behavior is very similar to an often reported "... New Formulation of gamma Z Box Corrections to the Weak Charge of the Proton [作者：Blunden, PG; Melnitchouk, W; Thomas, AW,期刊：PHYSICAL REVIEW LETTERS, 页码：81801-81801 , 文章类型： Article，,卷期：2011年107-8] We present a new formulation of one of the major radiative corrections to the weak charge of the proton-that arising from the axial-vector hadron part of the gamma Z box diagram, Re square(A)(gamma Z). This formulation, ...
