Macroscopic quantum dynamics of pi-junctions with ferromagnetic insulators [PDF]

, 2006
We theoretically investigate the macroscopic quantum dynamics of a pi junction with a superconductor (S) and a multiferroic material or a ferromagnetic insulator (FI).

Generating higher-order quantum dissipation from lower-order parametric processes [PDF]

, 2016
The stabilisation of quantum manifolds is at the heart of error-protected quantum information storage and manipulation. Nonlinear driven-dissipative processes achieve such stabilisation in a hardware efficient manner.

Initial-state dependence of thermodynamic dissipation for any quantum process. [PDF]

Physical Review E, 2020
Exact results about the nonequilibrium thermodynamics of open quantum systems at arbitrary timescales are obtained by considering all possible variations of initial conditions of a system.

Dynamics of Dissipative Quantum Hall Edges [PDF]

, 2003
We examine the influence of the edge electronic density profile and of dissipation on edge magnetoplasmons in the quantum Hall regime, in a semiclassical calculation.

Nonequilibrium steady states in the Floquet-Lindblad systems: van Vleck's high-frequency expansion approach

SciPost Physics Core, 2021
Nonequilibrium steady states (NESSs) in periodically driven dissipative quantum systems are vital in Floquet engineering. We develop a general theory for high-frequency drives with Lindblad-type dissipation to characterize and analyze NESSs.

QUANTUM DISSIPATION AND QUANTUM NOISE [PDF]

, 1995
We derive the exact action for a damped mechanical system ( and the special case of the linear oscillator) from the path integral formulation of the quantum Brownian motion problem developed by Schwinger and by Feynman and Vernon.

Engineering tunable local loss in a synthetic lattice of momentum states

New Journal of Physics, 2019
Dissipation can serve as a powerful resource for controlling the behavior of open quantum systems. Recently there has been a surge of interest in the influence of dissipative coupling on large quantum systems and, more specifically, how these processes ...

Non-Perturbative Renormalization Group Analysis of the Ohmic Quantum Dissipation

, 2003
We analyze quantum tunneling with the Ohmic dissipation by the non-perturbative renormalization group method. We calculate the localization susceptibility to evaluate the critical dissipation for the quantum-classical transition, and find considerably ...

Efficient simulation of non-Markovian system-environment interaction

New Journal of Physics, 2016
In this work, we combine an established method for open quantum systems—the time evolving density matrix using orthogonal polynomials algorithm—with the transfer tensors formalism, a new tool for the analysis, compression and propagation of non-Markovian

Probing eigenstate thermalization in quantum simulators via fluctuation-dissipation relations

Physical Review Research, 2020
The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the approach to equilibrium of closed quantum many-body systems. So far, however, experimental studies have focused on the relaxation dynamics of observables as described by ...
