代表性成果 1) 原子间长程相互作用可导致EJCH体系产生新奇量子相。对于确定温度下的一维情况，大尺寸体系可出现稳定的莫特绝缘相和超流相，而强的偶极-偶极相互作用可导致小尺寸的体系出现不稳定的密度波相。对于确定温度下的二维正方晶格体系，弱偶极-偶极相互作用可导致系统出现棋盘相和超流相；但在强偶极-偶极相互作用下，体系还可存在涨落和尺寸依赖性小的稳定超固相； 2) 显著的光力学耦合强度使得有效的格点排斥相互作用发生改变，导致高激发数的莫特绝缘相消失；腔光子-磁子的耦合强度的增加以及二者失谐为正可使 Mott 叶的稳定区域受到压缩，有利于体系相干；质心运动的 JCH 模型可出现莫特绝缘相，非相干振动，超流相和相干振动相四种量子相； 3) 长程相互作用会使体系发生拓扑相变，产生一个缠绕数为2的拓扑相；在拓扑态的转移过程中，长程相互作用会使末态等概率的占据在多个格点，形成拓扑路由器； 4) 偶偶极相互作用会导致弱隧穿极限下低密度 EJCH 模型中的中间态更接近可积点；费米近似后的 JCH 模型是近可积的并且不能热化；当光子的隧穿强度与光子-原子的耦合强度在同一量级时，JCH 系统在共振情况下出现量子混沌现象并且满足本征态热化假设； 5) 调控里德堡相互作用可实现三种不同频率光子实现量子路由；耗散会降低转移谱的峰值和全透射谱的峰值，对全反射谱的峰产生非对称影响； 6) 里德堡相互作用会使系统出现由能级非线性导致的常规光子阻塞效应和由不同路径之间的量子干涉导致的非常规光子阻塞效应； 7）基于一维非厄米模型来研究了广义布里渊区具有奇异特征情况下体边缘对应的物理性质。
