Mode-Locking of mobile discrete breathers
D. Zueco, P. J. Martinez, L. M. Floria +1
We study numerically synchronization phenomena of mobile discrete breathers in dissipative nonlinear lattices periodically forced. When varying the driving intensity, the breather…
Caldeira--Leggett quantum master equation in Wigner phase space: continued-fraction solution and application to Brownian motion in periodic potentials
J. L. Garcia-Palacios, D. Zueco
The continued-fraction method to solve classical Fokker--Planck equations has been adapted to tackle quantum master equations of the Caldeira--Leggett type. This can be done taking…
Nonlinear response of superparamagnets with finite damping: an analytical approach
J. L. Garcia-Palacios, D. A. Garanin
The strongly damping-dependent nonlinear dynamical response of classical superparamagnets is investigated by means of an analytical approach. Using rigorous balance equations for t…
Scale-Free topologies and Activatory-Inhibitory interactions
Jesus Gomez-Gardenes, Yamir Moreno, Luis Mario Floria
A simple model of activatory-inhibitory interactions controlling the activity of agents (substrates) through a "saturated response" dynamical rule in a scale-free network is thorou…
