研究了囚禁于远离共振的光势阱中的∧型冷原子与腔模相互作用系统.从Heisenberg—Langevin方程出发,在大失谐的条件下,绝热消除原子最高能级上的粒子布居数.在此情况下,通过进一步分析腔场算符和原子场算符的Heisenberg—Langevin方程,得出了该系统的有效哈密顿量.
We investigate the low temperature physics of ∧-type cold atoms trapped in optical lattice interacting with cavity modes. Starting from the Heisenberg-Langevin equations, we adiabatically eliminate the top atomic state at large atom-pump detuning. The effective Hamiltonian of the system can be obtained by analyzing the Heisenberg-Langevin equations of the cavity modes and the atom field operator.
