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 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…
A Comparison of Different Classical, Semiclassical and Quantum Treatments of Light-Matter Interactions: Understanding Energy Conservation
Tao E. Li, Hsing-Ta Chen, Joseph E. Subotnik
The optical response of an electronic two-level system (TLS) coupled to an incident continuous wave (cw) electromagnetic (EM) field is simulated explicitly in one dimension by the…
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…
Inchworm Monte Carlo for exact non-adiabatic dynamics I. Theory and algorithms
Hsing-Ta Chen, Guy Cohen, David R. Reichman
In this paper we provide a detailed description of the inchworm Monte Carlo formalism for the exact study of real-time non-adiabatic dynamics. This method optimally recycles Monte…
Inchworm Monte Carlo for exact non-adiabatic dynamics II. Benchmarks and comparison with established methods
Hsing-Ta Chen, Guy Cohen, David R. Reichman
In this second paper of a two part series, we present extensive benchmark results for two different inchworm Monte Carlo expansions for the spin-boson model. Our results are compar…
