Hierarchical quantum master equation with semiclassical Drude dissipation.
We propose a nonperturbative quantum dissipation theory, in term of hierarchical quantum master equation, which may be used with a great degree of confidence to various dynamics systems in condensed phases. The theoretical development is rooted in an improved semiclassical treatment of Drude bath, beyond the conventional high temperature approximations. It leads to the new theory a simple but i...
متن کاملBiexponential theory of Drude dissipation via hierarchical quantum master equation.
A nonperturbative quantum dissipation theory is developed based on an optimal construction of biexponential Drude bath correlation function for its influence on the system dynamics. It is an advanced hierarchical quantum master equation approach, aiming at a numerically efficient non-Markovian quantum dissipation propagator, with the support of a convenient criterion to estimate in advance its ...
متن کاملA semiclassical transport model for quantum cascade lasers based on the Pauli master equation
A semiclassical transport description based on the Pauli master equation (PME) is presented. A Monte Carlo simulator has been developed, which is an efficient approach for solving the PME and includes the most relevant scattering mechanisms. The proposed method has been used to simulate Quantum Cascade Lasers (QCLs) and allows the study of charge transport in an efficient way. As a prototypical...
متن کاملA semiclassical generalized quantum master equation for an arbitrary system-bath coupling.
The Nakajima-Zwanzig generalized quantum master equation (GQME) provides a general, and formally exact, prescription for simulating the reduced dynamics of a quantum system coupled to a, possibly anharmonic, quantum bath. In this equation, a memory kernel superoperator accounts for the influence of the bath on the dynamics of the system. In a previous paper [Q. Shi and E. Geva, J. Chem. Phys. 1...
متن کاملOptimized hierarchical equations of motion theory for Drude dissipation and efficient implementation to nonlinear spectroscopies.
Hierarchical equations of motion theory for Drude dissipation is optimized, with a convenient convergence criterion proposed in advance of numerical propagations. The theoretical construction is on the basis of a Padé spectrum decomposition that has been qualified to be the best sum-over-poles scheme for quantum distribution function. The resulting hierarchical dynamics under the a priori conve...
