摘要

将湮灭算符之间的递推关系应用于JCHM模型(JCHM)的跳跃相互作用项，将JCHM简化为普通的jayes - cummings模型(JCM)，尽管具有依赖于跳跃强度的玻色子能量。这使我们能够计算出莫特到超流体相变的相图以及作为失谐函数的临界跳变强度。

Particle-Hole Ansatz in the Jaynes-Cummings-Hubbard Model

A recurrence relation ansatz between annihilation operators applied to the hopping interaction term of the Jaynes-Cummings-Hubbard model (JCHM) reduces the JCHM to that of the ordinary Jaynes-Cummings model (JCM), albeit, with a boson energy depending on the hopping strength. This allows us to calculate the phase diagram for the Mott-to-superfluid phase transition and the critical hopping strength as a function of the detuning.
