论文摘要
我们分析了线性耦合的二元bose-Einstein冷凝物（BEC）诱导的自发对称性破坏（SSB）。该模型基于具有立方非线性的线性耦合schrödinger方程，并且仅作用于一个原子成分之一。通过数值模拟，获得了对称和非对称地面园，并观察到伴侣场中诱导的不对称性。从这个意义上讲，我们正确地证明了混合两场分量（RABI耦合）的线性耦合可以促进原子种类之间的（IN）平衡，以及Josephson和SSB相的外观。
We analyze the spontaneous symmetry breaking (SSB) induced by one specific component of a linearly coupled binary Bose-Einstein condensate (BEC). The model is based on linearly coupled Schrödinger equations with cubic nonlinearity and with a double-well (DW) potential acting on only one of the atomic components. By numerical simulations, symmetric and asymmetric ground-states were obtained, and an induced asymmetry in the partner field was observed. In this sense, we properly demonstrated that the linear coupling mixing the two-field component (Rabi coupling) promotes the (in)balance between atomic species, as well as the appearance of the Josephson and SSB phases.
