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…
Current induced magnetization switching in magnetic tunnel junctions
Z. F. Lin, S. T. Chui, L. B. Hu
A new mechanism different from the spin accumulation picture is proposed for the current induced magnetization switching in magnetic tunnel junctions by taking into account the eff…
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…
Nonlinear charging, and transport times in doped nanotubes junctions
Keivan Esfarjani, Amir A. Farajian, Siu Tat Chui +1
The nonlinear capacitance in doped nanotube junctions is calculated self consistently. It decreases as a function of the applied bias when the latter becomes larger than the pseudo…
Phase separation and vortex states in binary mixture of Bose-Einstein condensates in the trapping potentials with displaced centers
S. T. Chui, V. N. Ryzhov, E. E. Tareyeva
The system of two simultaneously trapped codensates consisting of atoms in two different hyperfine states is investigated theoretically in the case when the minima of the…
