Adiabaticity in Nonlinear Quantum Dynamics: Bose-Einstein Condensate in a Time-Varying Box
Y. B. Band, B. Malomed, M. Trippenbach
A simple model of an atomic Bose-Einstein condensate in a box whose size varies with time is studied to determine the nature of adiabaticity in the nonlinear dynamics obtained with…
Nonlinear parametric instability in double-well lattices
Jaroslav Riedel, Eva Majernikova, Boris A. Malomed
A possibility of a nonlinear resonant instability of uniform oscillations in dynamical lattices with harmonic intersite coupling and onsite nonlinearity is predicted. Numerical sim…
Stability of narrow beams in bulk Kerr-type nonlinear media
B. Malomed, K. Marinov, D. Pushkarov +1
We consider (2+1)-dimensional beams, whose transverse size may be comparable to or smaller than the carrier wavelength, on the basis of an extended version of the nonlinear Schrödi…
