复合玻色子的干涉

Interference of composite bosons

Thomas Brougham, Stephen M. Barnett, Igor Jex

摘要:

我们研究多玻色子干涉。一个哈密顿量,把成对的玻色子作为一个单一的复合玻色子。这个哈密顿量允许两对玻色子相互作用,就好像它们是两个单独的复合玻色子。我们发现,这导致复合玻色子表现出新的干涉效应,如Hong-Ou-Mandel干涉。然后,我们调查两个一般的复合玻色子之间的干扰的情况下的形式主义的推广。最后,我们展示了如何在双原子Dicke模型中实现复合玻色子之间的干涉。

英文摘要:

We investigate multi-boson interference. A Hamiltonian is presented that treats pairs of bosons as a single composite boson. This Hamiltonian allows two pairs of bosons to interact as if they were two single composite bosons. We show that this leads to the composite bosons exhibiting novel interference effects such as Hong-Ou-Mandel interference. We then investigate generalizations of the formalism to the case of interference between two general composite bosons. Finally, we show how one can realize interference between composite bosons in the two atom Dicke model.
