UV/vis-to-IR Photonic Down Conversion Mediated by Excited State Vibrational Polaritons
Connor K. Terry Weatherly, Justin Provazza, Emily A. Weiss +1
This work proposes a new photophysical phenomenon whereby UV/vis excitation of a molecule involving a Franck-Condon (FC) active vibration yields infrared (IR) emission by strong co…
Overcoming positivity violations for density matrices in surface hopping
Anna S. Bondarenko, Roel Tempelaar
Fewest-switches surface hopping (FSSH) has emerged as one of the leading methods for modeling the quantum dynamics of molecular systems. While its original formulation was limited…
A Mean-Field Treatment of Vacuum Fluctuations in Strong Light-Matter Coupling
Ming-Hsiu Hsieh, Alex Krotz, Roel Tempelaar
Mean-field mixed quantum--classical dynamics could provide a much-needed means to inexpensively model quantum electrodynamical phenomena, by describing the optical field and its va…
Chiral polaritons based on achiral Fabry-Perot cavities using apparent circular dichroism
Andrew H. Salij, Randall H. Goldsmith, Roel Tempelaar
Polariton states with high levels of chiral dissymmetry offer exciting prospects for quantum information, sensing, and lasing applications. Such dissymmetry must emanate from eithe…
Perturbation theory under the truncated Wigner approximation reveals how system-environment entanglement formation drives quantum decoherence
Justin Provazza, Roel Tempelaar
Quantum decoherence is the disappearance of simple phase relations within a discrete quantum system as a result of interactions with an environment. For many applications, the ques…
Treating geometric phase effects in nonadiabatic dynamics
Alex Krotz, Roel Tempelaar
We present an approach for eliminating the gauge freedom for derivative couplings in nonadiabatic dynamics in the presence of geometric phase effects. This approach relies on a bot…
