论文摘要
我们在量子模拟中提出了一个新的方向，该方向在光腔中使用多级原子作为工具箱，以设计新型的玻感模型类型，这些模型具有相关的跳跃过程，该工艺在由原子基态跨越的合成阶梯中使用。负责相关跳跃的基本机制是集体腔介导的相互作用，这些相互作用在遥远的极限下为激发水平的多种多样穿好了。通过使用两个激光驱动器将基态水平弱耦合到这些穿着的状态，并具有适当的引人注目，可以在抑制不希望的单粒子和基态水平的集体转移的同时，可以设计相关的跳跃过程。我们讨论了可以在合成阶梯中实现的丰富多体动力学，包括配对生产过程，手性传输和轻曲线相关扩散。后者说明，可以在具有完全集体互动的系统中设计有效的地方概念。
We propose a new direction in quantum simulation that uses multilevel atoms in an optical cavity as a toolbox to engineer new types of bosonic models featuring correlated hopping processes in a synthetic ladder spanned by atomic ground states. The underlying mechanisms responsible for correlated hopping are collective cavity-mediated interactions that dress a manifold of excited levels in the far detuned limit. By weakly coupling the ground state levels to these dressed states using two laser drives with appropriate detunings, one can engineer correlated hopping processes while suppressing undesired single-particle and collective shifts of the ground state levels. We discuss the rich many-body dynamics that can be realized in the synthetic ladder including pair production processes, chiral transport and light-cone correlation spreading. The latter illustrates that an effective notion of locality can be engineered in a system with fully collective interactions.
