Superradiant Solid in Cavity QED Coupled to a Lattice of Rydberg Gas
Xue-Feng Zhang, Qing Sun, Yu-Chuan Wen +3
We study an optical cavity coupled to a lattice of Rydberg atoms, which can be represented by a generalized Dicke model. We show that the competition between the atomic interaction…
Three-body interactions on a triangular lattice
Xue-Feng Zhang, Yu-Chuan Wen, Yue Yu
We analyze the hard-core Bose-Hubbard model with both the three-body and nearest neighbor repulsions on the triangular lattice. The phase diagram is achieved by means of the semi-c…
Static impurities in a supersolid of interacting hard-core bosons on a triangular lattice
Xue-Feng Zhang, Yu-Chuan Wen, Sebastian Eggert
We study the effect of impurities in a supersolid phase in comparison to the behavior in the solid and superfluid phases. A supersolid phase has been established for interacting ha…
Quantized squeezing and even-odd asymmetry of trapped bosons
Shijie Hu, Yuchuan Wen, Yue Yu +2
We investigate the exact nature of the superfluid-to-Mott-insulator crossover for interacting bosons on an optical lattice in a one-dimensional, harmonic trap by high-precision den…
Cold-atoms on a two-dimensional square optical lattice with an alternating potential
Huaiming Guo, Yuchuan Wen, Shiping Feng
The cold-atom on a two-dimensional square optical lattice is studied within the hard-core boson Hubbard model with an alternating potential. In terms of the quantum Monte Carlo met…
Solitons and vortices in an evolving Bose-Einstein condensate
Shi-Jie Yang, Quan-Sheng Wu, Shiping Feng +2
Spatiotemporal evolution of a confined Bose-Einstein condensate is studied by numerically integrating the time-dependent Gross-Pitaevskii equation. Self-interference between the su…
