During initial lithiation, a moving p... Magnonic Crystal as a Medium with Tunable Disorder on a Periodical Lattice [作者：Ding, J; Kostylev, M; Adeyeye, AO,期刊：PHYSICAL REVIEW LETTERS, 页码：47205-47205 , 文章类型： Article，,卷期：2011年107-4] We show that periodic magnetic nanostructures represent a perfect system for studying excitations on disordered periodical lattices because of the possibility of controlled variation of the degree of disorder by varying ...

Electrons tunneling through quasidegenerate states of a molecular junction exhibit inte... Spin Relaxation in Single-Layer and Bilayer Graphene [作者：Han, W; Kawakami, RK,期刊：PHYSICAL REVIEW LETTERS, 页码：47207-47207 , 文章类型： Article，,卷期：2011年107-4] We investigate spin relaxation in graphene spin valves and observe strongly contrasting behavior for single-layer graphene (SLG) and bilayer graphene (BLG). In SLG, the spin lifetime (tau(s)) varies linearly with the mom... Weber's Law for Biological Responses in Autocatalytic Networks of Chemical Reactions [作者：Inoue, M; Kaneko, K,期刊：PHYSICAL REVIEW LETTERS, 页码：48301-48301 , 文章类型： Article，,卷期：2011年107-4] Biological responses often obey Weber's law, according to which the magnitude of the response depends only on the fold change in the external input. In this study, we demonstrate that a system involving a simple autocata... Enhanced Photoinduced Desorption from Metal Nanoparticles by Photoexcitation of Confined Hot Electrons Using Femtosecond Laser Pulses [作者：Kim, KH; Watanabe, K; Mulugeta, D; Freund, HJ; Menzel, D,期刊：PHYSICAL REVIEW LETTERS, 页码：47401-47401 , 文章类型： Article，,卷期：2011年107-4] Strong fluence dependence of photodesorption cross sections is observed in femtosecond laser photodesorption of NO from (NO)(2) on silver nanoparticles, in contrast to femtosecond photodesorption on bulk metals. The time... Determination of the Defining Boundary in Nuclear Magnetic Resonance Diffusion Experiments [作者：Laun, FB; Kuder, TA; Semmler, W; Stieltjes, B,期刊：PHYSICAL REVIEW LETTERS, 页码：48102-48102 , 文章类型： Article，,卷期：2011年107-4] While nuclear magnetic resonance diffusion experiments are widely used to resolve structures confining the diffusion process, it has been elusive whether they can exactly reveal these structures. This question is closely... Multiple Bifurcation Types and the Linear Dynamics of Ion Sputtered Surfaces, (vol 101, 246102, 2008) [作者：Madi, CS; Davidovitch, B; George, HB; Norris, SA; Brenner, MP; Aziz, MJ,期刊：PHYSICAL REVIEW LETTERS, 页码：49902-49902 , 文章类型： Correction，,卷期：2011年107-4] Lagrangian Formulation of Turbulent Premixed Combustion [作者：Pagnini, G; Bonomi, E,期刊：PHYSICAL REVIEW LETTERS, 页码：44503-44503 , 文章类型： Article，,卷期：2011年107-4] The Lagrangian point of view is adopted to study turbulent premixed combustion. The evolution of the volume fraction of combustion products is established by the Reynolds transport theorem. It emerges that the burned-mas... Liquid-Gas Phase Separation in Confined Vibrated Dry Granular Matter [作者：Roeller, K; Clewett, JPD; Bowley, RM; Herminghaus, S; Swift, MR,期刊：PHYSICAL REVIEW LETTERS, 页码：48002-48002 , 文章类型： Article，,卷期：2011年107-4] A new phase transition is observed experimentally in a dry granular gas subject to vertical vibration between two horizontal plates. Molecular dynamics simulations of this system allow us to investigate the observed phas... Observation of Long Spin-Relaxation Times in Bilayer Graphene at Room Temperature [作者：Yang, TY; Balakrishnan, J; Volmer, F; Avsar, A; Jaiswal, M; Samm, J; Ali, SR; Pachoud, A; Zeng, M; Popinciuc, M; Guntherodt, G; Beschoten, B; Ozyilmaz, B,期刊：PHYSICAL REVIEW LETTERS, 页码：47206-47206 , 文章类型： Article，,卷期：2011年107-4] We report on the first systematic study of spin transport in bilayer graphene (BLG) as a function of mobility, minimum conductivity, charge density, and temperature. The spin-relaxation time tau(s) scales inversely with ...
