Stable and unstable regimes in Bose-Fermi mixture with attraction between components
A. M. Belemuk, S. -T. Chui, V. N. Ryzhov
A collapse of the trapped boson- fermion mixture with the attraction between bosons and fermions is investigated in the framework of the effective Hamiltonian for the Bose system.…
Vortex state in Bose-Fermi mixture with attraction between bosons and fermions
N. M. Chtchelkatchev, S. -T. Chui, V. N. Ryzhov
Vortex states in the mixture of ultracold atomic clouds of bosons and fermions are investigated using the effective Hamiltonian for the Bose subsystem. A stability of the Bose syst…
Collapse of Bose component in Bose-Fermi mixture with attraction between components
S. -T. Chui, V. N. Ryzhov, E. E. Tareyeva
An effective Hamiltonian for the Bose system in the mixture of ultracold atomic clouds of bosons and fermions is obtained by integrating out the Fermi degrees of freedom. An instab…
Insulator-Superfluid transition of spin-1 bosons in an optical lattice in magnetic field
A. A. Svidzinsky, S. T. Chui
We study the insulator-superfluid transition of spin-1 bosons in an optical lattice in a uniform magnetic field. Based on a mean-field approximation we obtained a zero-temperature…
Normal modes and stability of phase separated trapped Bose-Einstein condensates
Anatoly A. Svidzinsky, Siu-Tat Chui
We study the normal modes and the stability of two component condensates in a phase separated regime. In such a regime the system can undergo a quantum phase transition upon the ch…
Symmetric-Asymmetric transition in mixtures of Bose-Einstein condensates
Anatoly Svidzinsky, Siu-Tat Chui
We propose a new kind of quantum phase transition in phase separated mixtures of Bose-Einstein condensates. In this transition, the distribution of the two components changes from…
Collapse transition in mixtures of Bosons and Fermions
S. T. Chui, V. N. Ryzhov
For mixtures of Bose and Fermi alkali atoms, the Fermion degrees of freedom can be integrated out in their {\bf finite temperature} partition function. The final result can be expa…
Vortex states in binary mixture of Bose-Einstein condensates
S. T. Chui, V. N. Ryzhov, E. E. Tareyeva
The vortex configurations in the Bose-Einstein condensate of the mixture of two different spin states |F=1,m_f=-1> and |2,1> of ^{87}Rb atoms corresponding to the recent experiment…
Phase separation and vortex states in binary mixture of Bose-Einstein condensates
S. T. Chui, V. N. Ryzhov, E. E. Tareyeva
The phase separation and vortex states in two-component Bose-Einstein condensate consisting of and internal spin states of atoms are considered in…
Soliton and 2D domains in ultra-thin magnetic films
S. T. Chui, V. N. Ryzhov
We show that many two dimensional domain patterns observed in Monte Carlo simulations can be obtained from the many soliton solutions of the imaginary time Sine Gordon equation. Th…
