Rearrangement collisions between gold clusters
Jose Rogan, Ricardo Ramirez, Aldo H. Romero +1
Collision processes between two gold clusters are investigated using classical molecular dynamics in combination with embedded atom (EA) potentials, after checking the reliability…
First Passage Time Statistics For Systems Driven by Long Range Gaussian Noises
Aldo H. Romero, J. M. Sancho, Katja Lindenberg
We examine the mean first passage time for a particle driven by highly correlated Gaussian fluctuations to reach one or more predetermined boundaries. We discuss a numerical algori…
The breakdown of adiabatic polaron theory in one, two, and three dimensions and the reformation of the large polaron concept
Aldo H. Romero, David W. Brown, Katja Lindenberg
We prove variationally that at weak coupling in one, two, and three dimensions there exist correlated electron-phonon states below the approximate ground states characteristically…
Electronic Kinetic Energy in the Polaron Ground State and the Location of the Self-Trapping Transition
A. H. Romero, David W. Brown, Katja Lindenberg
In this paper we discuss the electronic kinetic energy in the ground state of the Holstein Hamiltonian in one space dimension using the Global-Local variational method together wit…
