Thermal conductance in thin wires with surface disorder
Gursoy B. Akguc, Jiangbin Gong
Elastic wave characteristics of the heat conduction in low-temperature thin wires can be studied via a wave scattering formalism. A reaction matrix formulation of heat conductance…
Symmetry Breaking and Self-trapping of a Dipolar Bose-Einstein Condensate in a Double-well Potential
Bo Xiong, Jiangbin Gong, Han Pu +2
The quantum self-trapping phenomenon of a Bose-Einstein condensate (BEC) represents a remarkable nonlinear effect of wide interest. By considering a purely dipolar BEC in a double-…
Formation and Transformation of Vector-Solitons in Two-Species Bose-Einstein Condensates with Tunable Interaction
Xunxu Liu, Han Pu, Bo Xiong +2
Under a unified theory we investigate the formation of various types of vector-solitons in two-species Bose-Einstein condensates with arbitrary scattering lengths. We then show tha…
Controlling the Population Imbalance of a Bose-Einstein Condensate by a Symmetry-Breaking Driving Field
Luis Morales-Molina, Jiangbin Gong
Nonlinear Floquet states associated with a symmetry-breaking driving field are exploited to control the dynamics of a Bose-Einstein condensate in a double-well potential. The popul…
Quantum Ratchet Accelerator without a Bichromatic Lattice Potential
Jiao Wang, Jiangbin Gong
In a quantum ratchet accelerator system, a linearly increasing directed current can be dynamically generated without using a biased field. Generic quantum ratchet acceleration with…
Nonlinear Landau-Zener Processes in a Periodic Driving Field
Qi Zhang, Peter Hanggi, Jiangbin Gong
Effects of a periodic driving field on Landau-Zener processes are studied using a nonlinear two-mode model that describes the mean-field dynamics of a many-body system. A variety o…
