Modulational instability of matter waves under strong nonlinearity management
F. Kh. Abdullaev, A. A. Abdumalikov, R. M. Galimzyanov
We study modulational instability of matter-waves in Bose-Einstein condensates (BEC) under strong temporal nonlinearity-management. Both BEC in an optical lattice and homogeneous B…
Collective excitations of BEC under anharmonic trap position jittering
F. Kh. Abdullaev, R. M. Galimzyanov, Kh. N. Ismatullaev
Collective excitations of a Bose-Einstein condensate under periodic oscillations of a quadratic plus quartic trap position has been studied. A coupled set of variational equations…
Gap solitons in Bose-Einstein condensates in linear and nonlinear optical lattices
Fatkhulla Abdullaev, Abdulaziz Abdumalikov, Ravil Galimzyanov
Properties of localized states on array of BEC confined to a potential, representing superposition of linear and nonlinear optical lattices are investigated. For a shallow lattice…
Resonances in a trapped 3D Bose-Einstein condensate under periodically varying atomic scattering length
Fatkhulla Kh. Abdullaev, Ravil M. Galimzyanov, Marijana Brtka +1
Nonlinear oscillations of a 3D radial symmetric Bose-Einstein condensate under periodic variation in time of the atomic scattering length have been studied analytically and numeric…
