Path integral approach to the Wigner representation of canonical density operators for discrete systems coupled to harmonic baths
Andrés Montoya-Castillo, David R. Reichman
We derive a semi-analytical form for the Wigner transform for the canonical density operator of a discrete system coupled to a harmonic bath based on the path integral expansion of…
Approximate but accurate quantum dynamics from the Mori formalism: II. Equilibrium correlation functions
Andrés Montoya-Castillo, David R. Reichman
The ability to efficiently and accurately calculate equilibrium time correlation functions of many-body condensed phase quantum systems is one of the outstanding problems in theore…
Generalized Quantum Master Equations In and Out of Equilibrium: When Can One Win?
Aaron Kelly, Andrés Montoya-Castillo, Lu Wang +1
Generalized quantum master equations (GQMEs) are an important tool in modeling chemical and physical processes. For a large number of problems it has been shown that exact and appr…
Approximate but Accurate Quantum Dynamics from the Mori Formalism: I. Nonequilibrium Dynamics
Andrés Montoya-Castillo, David. R. Reichman
We present a formalism that explicitly unifies the commonly used Nakajima-Zwanzig approach for reduced density matrix dynamics with the more versatile Mori theory in the context of…
