Non-adiabatic Dynamics in a Laser Field with Floquet Fewest Switches Surface Hopping: The Need for An Accurate Treatment of Coherence and Decoherence Remains
Zeyu Zhou, Hsing-Ta Chen, Abraham Nitzan +1
We investigate two well-known approaches for extending the fewest switches surface hopping (FSSH) algorithm to periodic time-dependent couplings. The first formalism acts as if the…
Understanding the Nature of Mean-Field Semiclassical Light-Matter Dynamics: An Investigation of Energy Transfer, Electron-Electron Correlations, External Driving and Long-Time Detailed Balance
Tao E. Li, Hsing-Ta Chen, Abraham Nitzan +1
Semiclassical electrodynamics is an appealing approach for studying light-matter interactions, especially for realistic molecular systems. However, there is no unique semiclassical…
Understanding Detailed Balance for an Electron-Radiation System Through Mixed Quantum-Classical Electrodynamics
Hsing-Ta Chen, Tao E. Li, Abraham Nitzan +1
We investigate detailed balance for a quantum system interacting with thermal radiation within mixed quantum-classical theory. For a two-level system coupled to classical radiation…
Electron transfer in confined electromagnetic fields
Alexander Semenov, Abraham Nitzan
The interaction between molecular (atomic) electron(s) and the vacuum field of a reflective cavity generates a significant interest thanks to the rapid developments in nanophotonic…
Predictive Semiclassical Model for Coherent and Incoherent Emission in the Strong Field Regime: The Mollow Triplet Revisited
Hsing-Ta Chen, Tao E. Li, Abraham Nitzan +1
We re-investigate the famous Mollow triplet and show that most of the well-known quantum characteristics of the Mollow triplet--including incoherent emission and a non-standard dep…
