Anomalous temperature dependence of the Casimir force for thin metal films
V. A. Yampol'skii, Sergey Savel'ev, Z. A. Mayselis +2
Within the framework of the Drude dispersive model, we predict an unusual non-monotonous temperature dependence of the Casimir force for thin metal films. For certain conditions, t…
Chirality tunneling and quantum dynamics for domain walls in mesoscopic ferromagnets
E. G. Galkina, B. A. Ivanov, Sergey Savel'ev +1
We studied the quantum dynamics of ferromagnetic domain walls (topological kink-type solitons) in one dimensional ferromagnetic spin chains. We show that the tunneling probability…
Quantum transport theory of anomalous electric, thermoelectric, and thermal Hall effects in ferromagnets
Shigeki Onoda, Naoyuki Sugimoto, Naoto Nagaosa
The mechanism of the anomalous Hall transport phenomena, if it is of the intrinsic or extrinsic origin, has been controversial. We present a unified theory of them for ferromagneti…
Forster mechanism of electron-driven proton pump
Anatoly Yu. Smirnov, Lev G. Mourokh, Franco Nori
We examine a simple model of proton pumping through the inner membrane of mitochondria in the living cell. We demonstrate that the pumping process can be described using approaches…
Lower limit on the achievable temperature in resonator-based sideband cooling
M. Grajcar, S. Ashhab, J. R. Johansson +1
A resonator can be effectively used as a cooler for another linear oscillator with a much smaller frequency. A huge cooling effect, which could be used to cool a mechanical oscilla…
Decoherence in a superconducting flux qubit with a pi-junction
T. Kato, A. A. Golubov, Y. Nakamura
We consider the use of a pi-junction for flux qubits to realize degenerate quantum levels without external magnetic field. On the basis of the Caldeira-Leggett model, we derive an…
Linear scaling calculation of a n-type GaAs quantum dot
Shintaro Nomura, Toshiaki Iitaka
A linear scale method for calculating electronic properties of large and complex systems is introduced within a local density approximation. The method is based on the Chebyshev po…
Observation of strong electron dephasing in disordered CuGeAu thin films
S. M. Huang, T. C. Lee, H. Akimoto +2
We report the observation of strong electron dephasing in a series of disordered CuGeAu thin films. A very short electron dephasing time possessing very weak tempera…
Cooling a Micromechanical Beam by Coupling it to a Transmission Line
Fei Xue, Y. D. Wang, Yu-xi Liu +1
We study a method to cool down the vibration mode of a micro-mechanical beam using a capacitively-coupled superconducting transmission line. The Coulomb force between the transmiss…
Microwave Absorption of Surface-State Electrons on Liquid He
Hanako Isshiki, Denis Konstantinov, Hikota Akimoto +2
We have investigated the intersubband transitions of surface state electrons (SSE) on liquid He induced by microwave radiation at temperatures from 1.1 K down to 0.01 K. Above…
Large nuclear Overhauser fields detected in vertically-coupled double quantum dots
J. Baugh, Y. Kitamura, K. Ono +1
We report the electrical induction and detection of dynamic nuclear polarization in the spin-blockade regime of double GaAs vertical quantum dots. The largest Overhauser field obse…
Spin effects in single-electron transport through carbon nanotube quantum dots
Satoshi Moriyama, Tomoko Fuse, Tomohiro Yamaguchi +1
We investigate the total spin in an individual single-wall carbon nanotube quantum dot with various numbers of electrons in a shell by using the ratio of the saturation currents of…
Gauge Field Formulation of Adiabatic Spin Torques
Hiroshi Kohno, Junya Shibata
Previous calculation of spin torques for small-amplitude magnetization dynamics around a uniformly magnetized state [J. Phys. Soc. Jpn. {\bf 75} (2006) 113706] is extended here to…
Current-induced vortex-vortex switching in a nanopillar comprising two Co nano-rings
T. Yang, A. Hirohata, M. Hara +2
We fabricated a current-perpendicular-to-plane pseudo-spin-valve nanopillar comprising a thick and a thin Co rings with deep submicron lateral sizes. The dc current can effectively…
Reversal of the circulation of a vortex by quantum tunneling in trapped Bose systems
Gentaro Watanabe, C. J. Pethick
We study the quantum dynamics of a model for a vortex in a Bose gas with repulsive interactions in an anisotropic, harmonic trap. By solving the Schrödinger equation numerically, w…
