AI 中文摘要
我们揭示手性腔区分二维电子气与腔真空之间的共振和反共振相互作用。对于同向旋转的螺旋度，模式发生反交叉，表现出真空拉比分裂，并保持裸真空基态。对于反向旋转的螺旋度，模式发生交叉，获得真空介导的能量位移和双模压缩基态。我们将这些观察的起源追溯到各自哈密顿量的SU(2)和SU(1,1)对称性，并展示了它们在手性光子晶体腔中的光谱特征。我们进一步预测，在有限的极化激元展宽下，腔手性会产生依赖于手性的霍尔电阻率修正，而在非手性腔中不存在这种修正。对于纵向电阻率，我们发现不同螺旋度下舒勃尼科夫-德哈斯振荡的不对称响应。最后，我们提出了一条通过电流涨落探测压缩基态的实验可行途径。基于最近展示的太赫兹手性腔的参数，这些效应在实验上可及。
英文摘要
We reveal that a chiral cavity distinguishes the resonant and antiresonant interactions between a two-dimensional electron gas and the cavity vacuum. For co-rotating helicities, the modes anticross, exhibiting vacuum Rabi splitting, and retain a bare vacuum ground state. For counter-rotating helicities, the modes cross, acquiring vacuum-mediated energy shifts and a two-mode squeezed ground state. We trace the origin of these observations to the SU(2) and SU(1,1) symmetries of the respective Hamiltonians and present their spectroscopic signatures in chiral photonic crystal cavities. We further predict that cavity chirality produces a handedness-dependent correction to Hall resistivity at finite polariton broadening, while such a correction is not present in an achiral cavity. For the longitudinal resistivity, we find an asymmetric response of the Shubnikov--de Haas oscillations for the different helicities. Finally, we present an experimentally accessible route for detecting the squeezed ground state through current fluctuations. Parameters based on a recently demonstrated terahertz chiral cavity place these effects within experimental reach.
