Resonant scattering of solitons
A. E. Miroshnichenko, S. Flach, B. Malomed
We study the scattering of solitons in the nonlinear Schroedinger equation on local inhomogeneities which may give rise to resonant transmission and reflection. In both cases, we d…
Wave scattering by discrete breathers
S. Flach, A. E. Miroshnichenko, M. V. Fistul
We present a theoretical study of linear wave scattering in one-dimensional nonlinear lattices by intrinsic spatially localized dynamic excitations or discrete breathers. These sta…
Incommensurate dynamics of resonant breathers in Josephson junction ladders
M. V. Fistul, A. E. Miroshnichenko, S. Flach +2
We present theoretical and experimental studies of resonant localized resistive states in a Josephson junction ladder. These complex breather states are obtained by tuning the brea…
AC-driven quantum spins: resonant enhancement of transverse DC magnetization
S. Flach, A. E. Miroshnichenko, A. A. Ovchinnikov
We consider s=1/2 spins in the presence of a constant magnetic field in z-direction and an AC magnetic field in the x-z plane. A nonzero DC magnetization component in y direction i…
Broken symmetries and directed collective energy transport
S. Flach, Y. Zolotaryuk, A. E. Miroshnichenko +1
We study the appearance of directed energy current in homogeneous spatially extended systems coupled to a heat bath in the presence of an external ac field E(t). The systems are de…
Breathers in Josephson junction ladders: resonances and electromagnetic waves spectroscopy
A. E. Miroshnichenko, S. Flach, M. V. Fistul +2
We present a theoretical study of the resonant interaction between dynamical localized states (discrete breathers) and linear electromagnetic excitations (EEs) in Josephson junctio…
