Rabi-induced localization and resonant delocalization of a binary condensate in a spin-asymmetric quasiperiodic potential
Swarup K. Sarkar, Sh. Mardonov, E. Ya. Sherman +1
We theoretically investigate the ground state and dynamics of a Rabi-coupled pseudospin-1/2 Bose-Einstein condensate, where only one spin component is subjected to an external pote…
Spin-dependent localization of spin-orbit and Rabi-coupled Bose-Einstein condensates in a random potential
Swarup K. Sarkar, Sh. Mardonov, E. Ya. Sherman +2
We investigate the effect of the spin-orbit (SO) and Rabi couplings on the localization of the spin-1/2 condensate trapped in a one-dimensional random potential. Our studies reveal…
Rabi-coupling driven motion of a soliton in a Bose-Einstein condensate
Sh. Mardonov, M. Modugno, E. Ya. Sherman +1
We study the motion of a self-attractive Bose-Einstein condensate with pseudo-spin 1/2 driven by a synthetic Rabi (Zeeman-like) field. This field triggers the pseudo-spin dynamics…
Spin-orbit coupled soliton in a random potential
Sh. Mardonov, V. V. Konotop, B. A. Malomed +2
We investigate theoretically the dynamics of a spin-orbit coupled soliton formed by a self- interacting Bose-Einstein condensate immersed in a random potential, in the presence of…
Dynamics of a macroscopic spin qubit in spin-orbit coupled Bose-Einstein condensates
Sh. Mardonov, M. Modugno, E. Ya. Sherman
We consider a macroscopic spin qubit based on spin-orbit coupled Bose-Einstein condensates, where, in addition to the spin-orbit coupling, spin dynamics strongly depends on the int…
Collapse of spin-orbit coupled Bose-Einstein condensates
Sh. Mardonov, E. Ya. Sherman, J. G. Muga +3
A finite-size quasi two-dimensional Bose-Einstein condensate collapses if the attraction between atoms is sufficiently strong. Here we present a theory of collapse for condensates…
The effects of disorder in dimerized quantum magnets in mean field approximations
Abdulla Rakhimov, Shuhrat Mardonov, E. Ya. Sherman +1
We study theoretically the effects of disorder on Bose-Einstein condensates (BEC) of bosonic triplon quasiparticles in doped dimerized quantum magnets. The condensation occurs in a…
Quasiequilibrium Mixture of Itinerant and Localized Bose Atoms in Optical Lattice
V. I. Yukalov, A. Rakhimov, S. Mardonov
Conditions are studied under which there can exist a quasiequilibrium mixture of itinerant and localized bosonic atoms in an optical lattice, even at zero temperature and at intege…
