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…
A Nonlinear Dynamical Model for Ultrafast Catalytic Transfer of Electrons at Zero Temperature
S. Aubry, G. Kopidakis
The complex amplitudes of the electronic wavefunctions on different sites are used as Kramers variables for describing Electron Transfer. The strong coupling of the electronic char…
Many-polaron states in the Holstein-Hubbard model
Laurent Proville, S. Aubry
A variational approach is proposed to determine some properties of the adiabatic Holstein-Hubbard model which describes the interactions between a static atomic lattice and an asse…
Aspects of Discrete Breathers and New Directions
S. Aubry, G. Kopidakis
We describe results concerning the existence proofs of Discrete Breathers (DBs) in the two classes of dynamical systems with optical linear phonons and with acoustic linear phonons…
