Symmetry in Full Counting Statistics, Fluctuation Theorem, and Relations among Nonlinear Transport Coefficients in the Presence of a Magnetic Field
Keiji Saito, Yasuhiro Utsumi
We study full counting statistics of coherent electron transport through multi-terminal interacting quantum-dots under a finite magnetic field. Microscopic reversibility leads to t…
Coherent destruction of tunneling, dynamic localization and the Landau-Zener formula
Yosuke Kayanuma, Keiji Saito
We clarify the internal relationship between the coherent destruction of tunneling (CDT) for a two-state model and the dynamic localization (DL) for a one-dimensional tight-binding…
Semiclassical Approach to Parametric Spectral Correlation with Spin 1/2
Taro Nagao, Keiji Saito
The spectral correlation of a chaotic system with spin 1/2 is universally described by the GSE (Gaussian Symplectic Ensemble) of random matrices in the semiclassical limit. In semi…
Fluctuation theorem in quantum heat conduction
Keiji Saito, Abhishek Dhar
We consider steady state heat conduction across a quantum harmonic chain connected to reservoirs modelled by infinite collection of oscillators. The heat, , flowing across the o…
Dissipative Landau-Zener transitions of a qubit: bath-specific and universal behavior
Keiji Saito, Martijn Wubs, Sigmund Kohler +2
We study Landau-Zener transitions in a qubit coupled to a bath at zero temperature. A general formula is derived that is applicable to models with a non-degenerate ground state. We…
