Gauging a quantum heat bath with dissipative Landau-Zener transitions
Martijn Wubs, Keiji Saito, Sigmund Kohler +2
We calculate the exact Landau-Zener transitions probabilities for a qubit with arbitrary linear coupling to a bath at zero temperature. The final quantum state exhibits a peculiar…
Semiclassical Theory for Parametric Correlation of Energy Levels
Taro Nagao, Petr Braun, Sebastian Müller +3
Parametric energy-level correlation describes the response of the energy-level statistics to an external parameter such as the magnetic field. Using semiclassical periodic-orbit th…
Quantum state preparation in circuit QED via Landau-Zener tunneling
Keiji Saito, Martijn Wubs, Sigmund Kohler +2
We study a qubit undergoing Landau-Zener transitions enabled by the coupling to a circuit-QED mode. Summing an infinite-order perturbation series, we determine the exact nonadiabat…
Asymmetric Heat Flow in Mesoscopic Magnetic System
Keiji Saito
The characteristics of heat flow in a coupled magnetic system are studied. The coupled system is composed of a gapped chain and a gapless chain. The system size is assumed to be qu…
