Theare mimicked in a potential hybrid quantum system, involving two ensembles of solid-state spins coupled to a pair of interconnected surface-acoustic-wave cavities. With the assistance of dichromatic classical optical drives featuring chiral designs, it can simulate two-mode LMG-type long-range spin-spin interactions with left-right asymmetry. For applications, this unconventional LMG model can not only engineer both ensembles of collective spins into two-mode spin-squeezed states but also simulate novel quantum critical phenomena and time crystal behaviors, among others. Since this acoustic-based system can generate ion-trap-like interactions without requiring any additional trapping techniques, our work is considered a fresh attempt at realizing chiral quantum manipulation of spin-spin interactions using acoustic hybrid systems.
在一个潜在的混合量子系统中可以模拟出这些情况，该系统涉及两组与一对相互连接的表面声波腔耦合的固态自旋。在具有手性设计的双色经典光驱动的辅助下，它可以模拟具有左右不对称性的双模LMG型长程自旋-自旋相互作用。在应用方面，这种非常规的LMG模型不仅可以将两组集体自旋都调控到双模自旋压缩态，还可以模拟新型量子临界现象和时间晶体行为等。由于这种基于声学的系统无需任何额外的俘获技术就能产生类似离子阱的相互作用，我们的工作被认为是利用声学混合系统实现自旋-自旋相互作用的手性量子操控的一次全新尝试。
