Enhanced Pulse Propagation in Non-Linear Arrays of Oscillators
A. Sarmiento, R. Reigada, A. H. Romero +1
The propagation of a pulse in a nonlinear array of oscillators is influenced by the nature of the array and by its coupling to a thermal environment. For example, in some arrays a…
Electron-Phonon Correlations, Polaron Size, and the Nature of the Self-Trapping Transition
A. H. Romero, David W. Brown, Katja Lindenberg
We analyze electron-phonon correlation functions measured in 1D polaron ground states of the Holstein Hamiltonian using the Global-Local variational method. The spatial collapse of…
One-Dimensional Arrays of Oscillators: Energy Localization in Thermal Equilibrium
R. Reigada, A. H. Romero, A. Sarmiento +1
All systems in thermal equilibrium exhibit a spatially variable energy landscape due to thermal fluctuations. Thus at any instant there is naturally a thermodynamically driven loca…
