Swanson哈密顿量:非PT对称相

Swanson Hamiltonian: non-PT-symmetry phase

V. Fernández, R. Ramírez, M. Reboiro

摘要:

在这项工作中,我们研究了非厄米斯旺森哈密顿量,特别是非PT对称相。我们利用Gel'fand三重态的形式构造了广义本征函数和相应的谱。根据参数模型空间的区域,我们表明斯旺森汉密尔顿表示不同的物理系统,即抛物垒、负质量振子。我们还讨论了无限级例外点的存在性。

英文摘要:

In this work, we study the non-hermitian Swanson hamiltonian, particularly the non-PT symmetry phase. We use the formalism of Gel'fand triplet to construct the generalized eigenfunctions and the corresponding spectrum. Depending on the region of the parameter model space, we show that the Swanson hamiltonian represents different physical systems, i.e. parabolic barrier, negative mass oscillators. We also discussed the presence of Exceptional Points of infinite order.
