含时哈密顿量下的无相互作用演化

Interaction-free evolution in the presence of time-dependent Hamiltonians

Dariusz Chruściński, Antonino Messina, Benedetto Militello, Anna Napoli

摘要:

无相互作用演化概念的推广[A. Napoli,{ \it et al.},Phys.Rev.A { \bf 89},062104(2014)]中的方法应用于时间依赖的哈密顿算子的情况。事实证明,依赖于时间的情况下,允许更丰富的结构的相互作用自由的状态和相互作用自由的子空间。发现了发生IFE的一般条件,并利用这些条件分析了具体情况。提出了几个例子,每一个相关的一类具有特定功能的哈密顿。

英文摘要:

The generalization of the concept of interaction-free evolutions (IFE) [A. Napoli, {\it et al.}, Phys. Rev. A {\bf 89}, 062104 (2014)] to the case of time-dependent Hamiltonians is discussed. It turns out that the time-dependent case allows for much more rich structures of interaction-free states and interaction-free subspaces. The general condition for the occurrence of IFE is found and exploited to analyze specific situations. Several examples are presented, each one associated to a class of Hamiltonians with specific features.
