玻色二次哈密顿量的Bogoliubov对角化

Diagonalization of bosonic quadratic Hamiltonians by Bogoliubov transformations

Phan Thành Nam, Marcin Napiórkowski, Jan Philip Solovej

摘要:

我们提供了一般的条件,玻色二次哈密顿Fock空间可以对角化的Bogoliubov变换。我们的结果覆盖的情况下,量子系统有无限的自由度和相关的一体动力学和配对运营商是无界的。我们的充分条件是最优的,在这个意义上,他们成为必要时,相关的一体运营商交换。

英文摘要:

We provide general conditions for which bosonic quadratic Hamiltonians on Fock spaces can be diagonalized by Bogoliubov transformations. Our results cover the case when quantum systems have infinite degrees of freedom and the associated one-body kinetic and paring operators are unbounded. Our sufficient conditions are optimal in the sense that they become necessary when the relevant one-body operators commute.
