Influence Functional Approach to Non-Perturbative Exciton Binding Renormalization from Phonons
Rohit Rana, Eric R. Heller, Antonios M. Alvertis +2
We construct a many-body model Hamiltonian to capture how phonons renormalize exciton binding as a function of temperature. By using the GW approximation and density functional per…
Pattern stability in reaction-diffusion systems depends on path entropy
Eric R. Heller, David T. Limmer
Reaction-diffusion systems driven far from thermodynamic equilibrium through the injection of energy can support multiple distinct spatial patterns that persist as long-lived dynam…
Instanton Theory for Nonadiabatic Tunneling through Near-Barrier Crossings
Ziyan Ye, Eric R. Heller, Dong H. Zhang +2
Many reactions in chemistry and biology involve multiple electronic states, rendering them nonadiabatic in nature. These reactions can be formally described using Fermi's golden ru…
Evaluation of transition rates from nonequilibrium instantons
Eric R. Heller, David T. Limmer
Equilibrium rate theories play a crucial role in understanding rare, reactive events. However, they are inapplicable to a range of irreversible processes in systems driven far from…
