PT对称性自发破缺的显式可解模型
An explicitly solvable model of the spontaneous PT-symmetry breaking
摘要：
我们考虑了一对纯虚δ函数势在有限区间上的Dirichlet边界条件。两个参数的模型表现出很好的预期的定量特征的不可避免的水平交叉和“相变”的复杂化的能量。结合分析和数值技术，我们调查的强度和位置依赖性的频谱。
英文摘要：
We contemplate the pair of the purely imaginary delta-function potentials on a finite interval with Dirichlet boundary conditions. The two parameter model exhibits nicely the expected quantitative features of the unavoided level crossing and of a "phase-transition" complexification of the energies. Combining analytic and numerical techniques we investigate strength- and position-dependence of its spectrum.
