Optical conductivity of the Frohlich polaron
A. S. Mishchenko, N. Nagaosa, N. V. Prokof'ev +2
We present accurate results for optical conductivity of the three dimensional Frohlich polaron in all coupling regimes. The systematic-error free diagrammatic quantum Monte Carlo m…
Scaling of the anomalous Hall effect in SrCaRuO
R. Mathieu, A. Asamitsu, H. Yamada +5
The anomalous Hall effect (AHE) of ferromagnetic thin films of SrCaRuO (0 0.4) is studied as a function of and temperature . As increases…
Interplay of Electron-Phonon Interaction and Electron Correlation in High Temperature Superconductivity
Sumio Ishihara, Naoto Nagaosa
We study the electron-phonon interaction in the strongly correlated superconducting cuprates. Two types of the electron-phonon interactions are introduced in the model; the d…
Anomalous Hall Effect and Magnetic Monopoles in Momentum-Space
Z. Fang, N. Nagaosa, K. S. Takahashi +7
Efforts to find the magnetic monopole in real space have been made in cosmic rays and in accelerators, but up to now there is no firm evidence for its existence due to the very hea…
SU(2) Non-Abelian Holonomy and Dissipationless Spin Current in Semiconductors
Shuichi Murakami, Naoto Nagaosa, Shou-Cheng Zhang
Following our previous work [S. Murakami, N. Nagaosa, S. C. Zhang, Science 301, 1348 (2003)] on the dissipationless quantum spin current, we present an exact quantum mechanical cal…
Dissipationless Quantum Spin Current at Room Temperature
Shuichi Murakami, Naoto Nagaosa, Shou-Cheng Zhang
While microscopic laws of physics are invariant under the reversal of the arrow of time, the transport of energy and information in most devices is an irreversible process. It is t…
