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 …

This review provides the fundamental theoretical tools for the development of a complete
wave‐function formalism for the study of time‐evolution of chemico‐physical systems at finite …

An open quantum system refers to a system that is further coupled to a bath system
consisting of surrounding radiation fields, atoms, molecules, or proteins. The bath system is …

We expand the standard thermodynamic framework of a system coupled to a thermal
reservoir by considering a stream of independently prepared units repeatedly put into …

We present the reaction-coordinate polaron-transform (RCPT) framework for generating
effective-Hamiltonian models to treat nonequilibrium open quantum systems at strong …

Deriving the laws of thermodynamics from a microscopic picture is a central quest of
statistical mechanics. This tutorial focuses on the derivation of the first and second law for …

A general thermodynamic framework is presented for open quantum systems in fixed contact
with a thermal reservoir. The first and second law are obtained for arbitrary system-reservoir …

Quantum systems strongly coupled to many-body systems equilibrate to the reduced state of
a global thermal state, deviating from the local thermal state of the system as it occurs in the …

Exceptional points (EPs) are singularities in the spectra of non-Hermitian operators where
eigenvalues and eigenvectors coalesce. Open quantum systems have recently been …

We establish a theoretical method which goes beyond the weak-coupling and Markovian
approximations while remaining intuitive, using a quantum master equation in a larger …
