Exact open quantum system dynamics using the Hierarchy of Pure States (HOPS)
Richard Hartmann, Walter T. Strunz
We show that the general and numerically exact Hierarchy of Pure States method (HOPS) is very well applicable to calculate the reduced dynamics of an open quantum system. In partic…
Including temperature in a wavefunction description of the dynamics of the quantum Rabi model
Michael Werther, Frank Grossmann
We present a wavefunction methodology to account for finite temperature initial conditions in the quantum Rabi model. The approach is based on the Davydov-Ansatz together with a st…
Application of the Mixed Time-averaging Semiclassical Initial Value Representation method to Complex Molecular Spectra
Max Buchholz, Frank Grossmann, Michele Ceotto
The recently introduced mixed time-averaging semiclassical initial value representation molecular dynamics method for spectroscopic calculations [M. Buchholz, F. Grossmann, and M.…
Stochastic Feshbach Projection for the Dynamics of Open Quantum Systems
Valentin Link, Walter T. Strunz
We present a stochastic projection formalism for the description of quantum dynamics in Bosonic or spin environments. The Schrödinger equation in coherent state representation with…
