非自伴哈密顿算符和双相干态的纠缠算符
Intertwining operators for non self-adjoint Hamiltonians and bicoherent states
摘要：
本文致力于构造我们称之为{ \em精确可解模型}的量子力学系统，即用一个Hamilton $H$描述的量子力学系统，它的本征值和本征向量可以显式地由一些{ \em极小成分}构造出来。特别地，受PT-量子力学的启发，我们将不坚持在我们的构造中考虑的哈密顿量的任何自伴性特征。我们还介绍了所谓的双相干态，我们分析了它们的一些属性，我们展示了它们如何可以用于量化系统。一些例子，在有限和无限维希尔伯特空间，进行了讨论。
英文摘要：
This paper is devoted to the construction of what we will call {\em exactly solvable models}, i.e. of quantum mechanical systems described by an Hamiltonian $H$ whose eigenvalues and eigenvectors can be explicitly constructed out of some {\em minimal ingredients}. In particular, motivated by PT-quantum mechanics, we will not insist on any self-adjointness feature of the Hamiltonians considered in our construction. We also introduce the so-called bicoherent states, we analyze some of their properties and we show how they can be used for quantizing a system. Some examples, both in finite and in infinite-dimensional Hilbert spaces, are discussed.
