For describing a coherent quantum two-level system driven by a linearly time-dependent
energy separation of the diabatic states, the Landau-Zener model is routine to serve as a …

In this paper we investigate the ground-state properties and related quantum phase
transitions for the two-component Bose-Einstein condensate in a single-mode optical cavity …

We propose a scheme which can realize an extended two-component Bose-Hubbard model
using polaritons confined in an array of optical cavities. In addition to the density-dependent …

We propose a theoretical model of a system of two quantum states, coupled by tunneling of
correlated pairs of Bose particles. Cavity polaritons in a rectangular potential trap are …

研究了单模光腔中两组分玻色-爱因斯坦凝聚的基态性质和相关的量子相变.
通过利用自旋相干态变换将等效赝自旋哈密顿算符对角化并求得基态能量泛函 …
