Quantum dissipation with conditional wave functions: Application to the realistic simulation of nanoscale electron devices [PDF]

open access: yes, 2017
Without access to the full quantum state, modeling dissipation in an open system requires approximations. The physical soundness of such approximations relies on using realistic microscopic models of dissipation that satisfy completely positive dynamical

Fractional Quantum Zeno Effect Emerging from Non-Hermitian Physics

open access: yesPhysical Review X, 2023
Exploring non-Hermitian phenomenology is an exciting frontier of modern physics. However, the demonstration of a non-Hermitian phenomenon that is quantum in nature has remained elusive.

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

open access: yes, 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]

open access: yes, 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.

Timescales of Quantum Equilibration, Dissipation and Fluctuation in Nuclear Collisions. [PDF]

open access: yesPhysical Review Letters, 2020
Understanding the dynamics of equilibration processes in quantum systems as well as their interplay with dissipation and fluctuation is a major challenge in quantum many-body theory.

Dynamics of Dissipative Quantum Hall Edges [PDF]

open access: yes, 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.

DISSIPATIVE QUANTUM DISORDERED MODELS [PDF]

open access: yesRecent Progress in Many-Body Theories, 2006
This article reviews recent studies of mean-field and one dimensional quantum disordered spin systems coupled to different types of dissipative environments. The main issues discussed are: (i) The real-time dynamics in the glassy phase and how they compare to the behaviour of the same models in their classical limit.

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

open access: yesSciPost 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.

Engineering tunable local loss in a synthetic lattice of momentum states

open access: yesNew 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 ...
