Effects of disorder on quantum fluctuations and superfluid density of a Bose-Einstein condensate in a two-dimensional optical lattice
Ying Hu, Zhaoxin Liang, Bambi Hu
We investigate a Bose-Einstein condensate trapped in a 2D optical lattice in the presence of weak disorder within the framework of the Bogoliubov theory. In particular, we analyze…
Power-dependent soliton steering in thermal nonlinear media
Fangwei Ye, Yaroslav V. Kartashov, Bambi Hu +1
We address the existence and properties of optical solitons excited in thermal nonlinear media with a transverse refractive index gradient. We show that in such a geometry one can…
Ballistic Thermal Transistor of Dielectric Four-terminal Nanostructures
Ping Yang, Bambi Hu
We report a theoretical model for a thermal transistor in dielectric four-terminal nanostructures based on mesoscopic ballistic phonon transport, in which a steady thermal flow con…
Light bullets in Bessel optical lattices with spatially modulated nonlinearity
Fangwei Ye, Yaroslav V. Kartashov, Bambi Hu +1
We address the stability of light bullets supported by Bessel optical lattices with out-of-phase modulation of the linear and nonlinear refractive indices. We show that spatial mod…
Negative differential thermal resistance induced by ballistic transport
Wei-Rong Zhong, Ping Yang, Bao-Quan Ai +2
Using nonequilibrium molecular-dynamics simulations, we study the temperature dependence of the negative differential thermal resistance that appears in two-segment Frenkel-Kontoro…
Elliptic Vortices in Composite Mathieu Lattices
Fangwei Ye, Dumitru Mihalache, Bambi Hu
We address the elliptically shaped vortex solitons in defocusing nonlinear media imprinted with a composite Mathieu lattice. Elliptic vortices feature anisotropic patterns both in…
