A partially linearized mapping approach to surface hopping (MASH-PLDM) for nonadiabatic dynamics and nonlinear spectroscopy
Jan Obermeier, Kasra Asnaashari, Jeremy O. Richardson
We derive a partially linearized version of the mapping approach to surface hopping (MASH) that provides a new method for simulating nonadiabatic dynamics in molecular systems. As…
Multidimensional tunnelling of molecules aligned by strong electric fields
J. Amira Geuther, Marit R. Fiechter, Jeremy O. Richardson
Strong electric fields can be used to align molecules. However, a non-polar molecule such as H has no preference for its orientation. There are thus two equivalent configuratio…
Open quantum-classical systems: A hybrid MASH master equation
Kasra Asnaashari, Jeremy O. Richardson
We propose a method which combines the quantum-classical mapping approach to surface hopping (MASH) with the dissipative quantum dynamics of the Lindblad master equation. Like conv…
Machine learning meets Lie algebra: Enhancing quantum dynamics learning with exact trace conservation
Arif Ullah, Jeremy O. Richardson
Machine learning (ML) has emerged as a promising tool for simulating quantum dissipative dynamics. However, existing methods often struggle to enforce key physical constraints, suc…
