- Observation of the Kondo Effect in a Spin-3/2 Hole Quantum Dot
[作者:Klochan, O; Micolich, AP; Hamilton, AR; Trunov, K; Reuter, D; Wieck, AD,期刊:PHYSICAL REVIEW LETTERS, 页码:76805-76805 , 文章类型: Article,,卷期:2011年107-7]
- We report the observation of Kondo physics in a spin-3/2 hole quantum dot. The dot is formed close to pinch-off in a hole quantum wire defined in an undoped AlGaAs/GaAs heterostructure. We clearly observe two distinctive...
- Ultrafast Transport of Laser-Excited Spin-Polarized Carriers in Au/Fe/MgO(001)
[作者:Melnikov, A; Razdolski, I; Wehling, TO; Papaioannou, ET; Roddatis, V; Fumagalli, P; Aktsipetrov, O; Lichtenstein, AI; Bovensiepen, U,期刊:PHYSICAL REVIEW LETTERS, 页码:76601-76601 , 文章类型: Article,,卷期:2011年107-7]
- Hot carrier-induced spin dynamics is analyzed in epitaxial Au/Fe/MgO(001) by a time domain approach. We excite a spin current pulse in Fe by 35 fs laser pulses. The transient spin polarization, which is probed at the Au ...
- Repulsive Contact Interactions Make Jammed Particulate Systems Inherently Nonharmonic
[作者:Schreck, CF; Bertrand, T; O'Hern, CS; Shattuck, MD,期刊:PHYSICAL REVIEW LETTERS, 页码:78301-78301 , 文章类型: Article,,卷期:2011年107-7]
- Many jammed particulate systems, such as granular and colloidal materials, interact via repulsive contact forces. We find that these systems possess no harmonic regime in the large system limit (N -> infinity) for all co...
- Optical Conductivity of the Holstein Polaron
[作者:Goodvin, GL; Mishchenko, AS; Berciu, M,期刊:PHYSICAL REVIEW LETTERS, 页码:76403-76403 , 文章类型: Article,,卷期:2011年107-7]
- The momentum average approximation is used to derive a new kind of nonperturbational analytical expression for the optical conductivity (OC) of a Holstein polaron at zero temperature. This provides insight into the shape...
- Flow of a Single Magnetic Vortex in a Submicron-Size Superconducting Al Disk Controlled by Radio-Frequency Currents
[作者:Harada, A; Enomoto, K; Takahide, Y; Kimata, M; Yakabe, T; Kodama, K; Satsukawa, H; Kurita, N; Tsuchiya, S; Terashima, T; Uji, S,期刊:PHYSICAL REVIEW LETTERS, 页码:77002-77002 , 文章类型: Article,,卷期:2011年107-7]
- We report the first observation of a single-vortex flow in a mesoscopic superconductor. A flow of a single vortex is successfully controlled by an rf current superimposed on a dc current, evidence of which is provided by...
- Structural Description of the Macroscopic Piezo- and Ferroelectric Properties of Lead Zirconate Titanate
[作者:Hinterstein, M; Rouquette, J; Haines, J; Papet, P; Knapp, M; Glaum, J; Fuess, H,期刊:PHYSICAL REVIEW LETTERS, 页码:77602-77602 , 文章类型: Article,,卷期:2011年107-7]
- An in situ structural description of the origin of the ferroelectric properties as a function of the applied electric field E was obtained by synchrotron x-ray diffraction. A setup was used to average the effects of the ...
- Demonstration of a Single-Photon Router in the Microwave Regime
[作者:Hoi, IC; Wilson, CM; Johansson, G; Palomaki, T; Peropadre, B; Delsing, P,期刊:PHYSICAL REVIEW LETTERS, 页码:73601-73601 , 文章类型: Article,,卷期:2011年107-7]
- We have embedded an artificial atom, a superconducting transmon qubit, in an open transmission line and investigated the strong scattering of incident microwave photons (similar to 6 GHz). When an input coherent state, w...
- Common Origin of the Circular-Dichroism Pattern in Angle-Resolved Photoemission Spectroscopy of SrTiO(3) and Cu(x)Bi(2)Se(3)
[作者:Ishida, Y; Kanto, H; Kikkawa, A; Taguchi, Y; Ito, Y; Ota, Y; Okazaki, K; Malaeb, W; Mulazzi, M; Okawa, M; Watanabe, S; Chen, CT; Kim, M; Bell, C; Kozuka, Y; Hwang, HY; Tokura, Y; Shin, S,期刊:PHYSICAL REVIEW LETTERS, 页码:77601-77601 , 文章类型: Article,,卷期:2011年107-7]
- Circular dichroism in the angular distribution of photoelectrons from SrTiO(3): Nb and Cu(x)Bi(2)Se(3) is investigated by 7-eV laser angle-resolved photoemission spectroscopy. In addition to the well-known node that occu...
- First Observational Tests of Eternal Inflation
[作者:Feeney, SM; Johnson, MC; Mortlock, DJ; Peiris, HV,期刊:PHYSICAL REVIEW LETTERS, 页码:71301-71301 , 文章类型: Article,,卷期:2011年107-7]
- The eternal inflation scenario predicts that our observable Universe resides inside a single bubble embedded in a vast inflating multiverse. We present the first observational tests of eternal inflation, performing a sea...
