A quantum dissipation theory is constructed with the system–bath interaction being treated rigorously at the second-order cumulant level for both reduced dynamics and initial canonical boundary condition. The theory is valid for arbitrary bath correlation functions and time-dependent external driving fields, and satisfies correlated detailed-balance relation at any temperatures. The general formulation assumes a particularly simple form in driven Brownian oscillator systems in which the…

The final residue-corrected hierarchical equations of motion can be used practically for the evaluation of arbitrary dissipative quantum systems, and the corresponding continued-fraction Green's functions formalism for quantum dissipation is presented.
Exact quantum dissipative dynamics under external time-dependent driving fields
An exact and nonperturbative quantum master equation can be constructed via the calculus on the path integral. It results in hierarchical equations of motion for the reduced density operator.
Time-dependent density functional theory for open quantum systems with unitary propagation.
We extend the Runge-Gross theorem for a very general class of open quantum systems under weak assumptions about the nature of the bath and its coupling to the system. We show that for Kohn-Sham (KS)
Dissipaton dynamics theory versus quantum master equations
Abstract In this review article we present first a comprehensive account on the recently developed the dissipaton-equation-of-motion (DEOM) theory. This is a statistical quasi-particle theory for

The projection operator technique is used to derive the exact quantum master equations of a qubit system with both diagonal splitting and tunneling coupling when the environmental noise is subject to a random telegraph process and a Ornstein-Uhlenbeck process.
Quantum mechanics of dissipative systems.
This review examines both theoretical and application aspects on various perturbative formulations, especially those that are exact up to second-order but nonequivalent in high-order system-bath coupling contributions.
Open quantum systems in Heisenberg picture
In the framework of Heisenberg picture, an alternative derivation of reduced density matrix of a driven quantum system interacting with its environment is presented. To illustrate the approach, the

The present theory renders an exact and numerically tractable tool to evaluate various transient and stationary quantum transport properties of many-electron systems, together with the involving nonperturbative dissipative dynamics.
Time-Local Quantum Master Equations and their Applications to Dissipative Dynamics and Molecular Wires
The dynamics in open quantum systems is often described by quantum master equations (QMEs). Here a certain class of these master equations, the socalled time-local or time-convolutionless QMEs, are

This paper renders two main results. One is a unified quantum master equation, which satisfies the detailed-balance relation and can serve as a convenient starting formulation to study the
