A simple improved low temperature correction for the hierarchical equations of motion

TP Fay - The Journal of Chemical Physics, 2022 - pubs.aip.org
The study of open system quantum dynamics has been transformed by the hierarchical
equations of motion (HEOM) method, which gives the exact dynamics for a system coupled …

Investigating the collective nature of cavity-modified chemical kinetics under vibrational strong coupling

LP Lindoy, A Mandal, DR Reichman - Nanophotonics, 2024 - degruyter.com
In this paper, we develop quantum dynamical methods capable of treating the dynamics of
chemically reacting systems in an optical cavity in the vibrationally strong-coupling (VSC) …

Time evolution of ML-MCTDH wavefunctions. II. Application of the projector splitting integrator

LP Lindoy, B Kloss, DR Reichman - The Journal of Chemical Physics, 2021 - pubs.aip.org
The multi-layer multi-configuration time-dependent Hartree (ML-MCTDH) approach can
suffer from numerical instabilities whenever the wavefunction is weakly entangled. These …
