PT对称振子的产生和湮灭算符及相干态

Creation and annihilation operators and coherent states for the PT-symmetric oscillator

B. Bagchi, C. Quesne

摘要:

我们构造了PT对称振子的两个可交换的产生算符和湮灭算符集。然后,我们建立相干态,后者作为本征态的这种湮没运营商通过采用修改后的版本的归一化积分,是相关的PT对称系统。我们证明了相干态仅在耦合参数$α$的范围(0,1)内是可归一化的。

英文摘要:

We construct two commuting sets of creation and annihilation operators for the PT-symmetric oscillator. We then build coherent states of the latter as eigenstates of such annihilation operators by employing a modified version of the normalization integral that is relevant to PT-symmetric systems. We show that the coherent states are normalizable only in the range (0, 1) of the underlying coupling parameter $α$.
