Diffusion without Spreading of a Wave Packet in Nonlinear Random Models
Serge J. Aubry
We discuss the long time behaviour of a finite energy wave packet in nonlinear Hamiltonians on infinite lattices at arbitrary dimension, exhibiting linear Anderson localization. St…
A semiclassical non-adiabatic theory for elementary chemical reactions
Serge Aubry
Electron Transfer (ET) reactions are modeled by the dynamics of a quantum two-level system (representing the electronic state) coupled to a thermalized bath of classical harmonic o…
A Unified Theory of Chemical Reactions
S. Aubry
We propose a new and general formalism for elementary chemical reactions where quantum electronic variables are used as reaction coordinates. This formalism is in principle applica…
Asymptotic energy profile of a wavepacket in disordered chains
S. Lepri, R. Schilling, S. Aubry
We investigate the long time behavior of a wavepacket initially localized at a single site in translationally invariant harmonic and anharmonic chains with random interaction…
Transmission thresholds in time-periodically driven nonlinear disordered systems
Magnus Johansson, Georgios Kopidakis, Stefano Lepri +1
We study energy propagation in locally time-periodically driven disordered nonlinear chains. For frequencies inside the band of linear Anderson modes, three different regimes are o…
Absence of Wavepacket Diffusion in Disordered Nonlinear Systems
G. Kopidakis, S. Komineas, S. Flach +1
We study the spreading of an initially localized wavepacket in two nonlinear chains (discrete nonlinear Schroedinger and quartic Klein-Gordon) with disorder. Previous studies sugge…
