Targeted energy transfer dynamics and chemical reactions
N. Almazova, S. Aubry, G. P. Tsironis
Ultrafast reaction processes take place when resonant features of nonlinear model systems are taken into account. In the targeted energy or electron transfer dimer model this is ac…
KAM tori in 1D random discrete nonlinear Schrödinger model?
Magnus Johansson, Georgios Kopidakis, Serge Aubry
We suggest that KAM theory could be extended for certain infinite-dimensional systems with purely discrete linear spectrum. We provide empirical arguments for the existence of squa…
Anomalous Thermostat and Intraband Discrete Breathers
S. Aubry, R. Schilling
We investigate the dynamics of a macroscopic system which consists of an anharmonic subsystem embedded in an arbitrary harmonic lattice, including quenched disorder. Elimination of…
Oscillatory Instabilities of Standing Waves in One-Dimensional Nonlinear Lattices
Anna Maria Morgante, Magnus Johansson, Georgios Kopidakis +1
In one-dimensional anharmonic lattices, we construct nonlinear standing waves (SWs) reducing to harmonic SWs at small amplitude. For SWs with spatial periodicity incommensurate wit…
Discrete Nonlinear Schr{ö}dinger Breathers in a Phonon Bath
K. Ø. Rasmussen, S. Aubry, A. R. Bishop +1
We study the dynamics of the discrete nonlinear Schr{ö}dinger lattice initialized such that a very long transitory period of time in which standard Boltzmann statistics is insuffic…
Manifestation of classical bifurcation in the spectrum of the integrable quantum dimer
S. Aubry, S. Flach, K. Kladko +1
We analyze the classical and quantum properties of the integrable dimer problem. The classical version exhibits exactly one bifurcation in phase space, which gives birth to permuta…
