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…
