Based on Richardson's exact solution of the multilevel pairing model we derive a new class of exactly solvable models for the finite boson system. As an example we solve a particular Hamiltonian which displays a transition to a fragmented condensate for repulsive pairing interaction.
基于理查森对多能级配对模型的精确解，我们为有限玻色子系统推导了一类新的精确可解模型。作为一个例子，我们求解了一个特定的哈密顿量，它展示了在排斥性配对相互作用下向碎片化凝聚态的转变。
