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…
Non conservation of the magnetization current across magnetic hetero-structures
S. T. Chui, Z. F. Lin
We show that when the magnetizations on opposite sides of a junction are not collinear, the magnetization current is not conserved as the junction is crossed. Thus the usual treatm…
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…
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…
Quantum Spinodal Decomposition in Multicomponent Bose-Einstein Condensates
S. T. Chui, P. Ao
We investigate analytically the non-equilibrium spatial phase segregation process of a mixture of alkali Bose-Einstein condensates. Two stages (I and II) are found in analogy to th…
