具有复特征值的非自伴Hamilton算子

Non self-adjoint Hamiltonians with complex eigenvalues

Fabio Bagarello

摘要:

受PT对称量子力学的影响,我们讨论了如果一个物理系统由一个可对角化的哈密顿量驱动,而不是所有的实本征值,会发生什么。特别是,我们考虑的功能结构有关的系统生活在有限维希尔伯特空间,我们表明,在这种情况下,如果我们引入合适的反线性算子,也可以推导出一定的交织关系。我们还分析了一个简单的模型,计算在破碎和未破碎的政权的转移概率。

英文摘要:

Motivated by what one observes dealing with PT-symmetric quantum mechanics, we discuss what happens if a physical system is driven by a diagonalizable Hamiltonian with not all real eigenvalues. In particular, we consider the functional structure related to systems living in finite-dimensional Hilbert spaces, and we show that certain intertwining relations can be deduced also in this case if we introduce suitable antilinear operators. We also analyze a simple model, computing the transition probabilities in the broken and in the unbroken regime.
