Non-hermitian physics

Y Ashida, Z Gong, M Ueda - Advances in Physics, 2020 - Taylor & Francis
A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

Enhanced light–matter interaction in two-dimensional transition metal dichalcogenides

L Huang, A Krasnok, A Alú, Y Yu… - Reports on Progress …, 2022 - iopscience.iop.org
Abstract Two-dimensional (2D) transition metal dichalcogenide (TMDC) materials, such as
MoS 2, WS 2, MoSe 2, and WSe 2, have received extensive attention in the past decade due …

Quantum engines and refrigerators

LM Cangemi, C Bhadra, A Levy - Physics Reports, 2024 - Elsevier
Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

Open quantum system dynamics and the mean force Gibbs state

AS Trushechkin, M Merkli, JD Cresser… - AVS Quantum Science, 2022 - pubs.aip.org
The dynamical convergence of a system to the thermal distribution, or Gibbs state, is a
standard assumption across all of the physical sciences. The Gibbs state is determined just …

Mpemba effects in open nonequilibrium quantum systems

A Nava, R Egger - Physical Review Letters, 2024 - APS
We generalize the classical thermal Mpemba effect (where an initially hot system relaxes
faster to the final equilibrium state than a cold one) to open quantum systems coupled to …

Unified Gorini-Kossakowski-Lindblad-Sudarshan quantum master equation beyond the secular approximation

A Trushechkin - Physical Review A, 2021 - APS
Derivation of a quantum master equation for a system weakly coupled to a bath which takes
into account nonsecular effects, but nevertheless has the mathematically correct Gorini …

Collision models can efficiently simulate any multipartite Markovian quantum dynamics

M Cattaneo, G De Chiara, S Maniscalco, R Zambrini… - Physical Review Letters, 2021 - APS
We introduce the multipartite collision model, defined in terms of elementary interactions
between subsystems and ancillas, and show that it can simulate the Markovian dynamics of …

Fundamental limitations in Lindblad descriptions of systems weakly coupled to baths

D Tupkary, A Dhar, M Kulkarni, A Purkayastha - Physical Review A, 2022 - APS
It is very common in the literature to write a Markovian quantum master equation in Lindblad
form to describe a system with multiple degrees of freedom and weakly connected to …

Combining critical and quantum metrology

C Hotter, H Ritsch, K Gietka - Physical Review Letters, 2024 - APS
Critical metrology relies on the precise preparation of a system in its ground state near a
quantum phase transition point where quantum correlations get very strong. Typically, this …

Quantum simulation of dissipative collective effects on noisy quantum computers

M Cattaneo, MAC Rossi, G García-Pérez, R Zambrini… - Prx quantum, 2023 - APS
Dissipative collective effects are ubiquitous in quantum physics and their relevance ranges
from the study of entanglement in biological systems to noise mitigation in quantum …
