Configuration interaction approaches for solving quantum impurity models
Zuxin Jin, Wenjie Dou, Joseph E. Subotnik
We develop several configuration interaction approaches for characterizing the electronic structure of an adsorbate on a metal surface (at least in model form). When one can separa…
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…
Quasiclassical Modeling of Cavity Quantum Electrodynamics
Tao E. Li, Hsing-Ta Chen, Abraham Nitzan +1
We model a collection of two-level systems (TLSs) coupled to a multimode cavity via Meyer-Miller-Stock-Thoss (MMST) dynamics, sampling both electronic and photonic zero-point e…
A Robust and Unified Solution for Choosing the Phases of Adiabatic States as a Function of Geometry: Extending Parallel Transport Concepts to the cases of Trivial & Near Trivial Crossings
Zeyu Zhou, Zuxin Jin, Tian Qiu +2
We investigate a simple and robust scheme for choosing the phases of adiabatic electronic states smoothly (as a function of geometry) so as to maximize the performance of ab initio…
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…
A Demonstration of Consistency between the Quantum Classical Liouville Equation and Berry's Phase and Curvature
Joseph Subotnik, Gaohan Miao, Nicole Bellonzi +2
Although the quantum classical Liouville equation (QCLE) arises by cutting off the exact equation of motion for a coupled nuclear-electronic system at order 1 (1 = ), we…
