Phase and amplitude modes, also called polariton modes, are emergent phenomena that manifest across diverse physical systems, from condensed matter and particle physics to quantum optics. We study their behavior in an anisotropic Dicke model that includes collective matter interactions. We study the low-lying spectrum in the thermodynamic limit via the Holstein-Primakoff transformation and contrast the results with the semi-classical energy surface obtained via coherent states. We also explore the geometric phase for both boson and spin contours in the parameter space as a function of the phases in the system. We unveil novel phenomena due to the unique critical features provided by the interplay between the anisotropy and matter interactions. We expect our results to serve the observation of phase and amplitude modes in current quantum information platforms.
相位和振幅模式，也称为极化激元模式，是在从凝聚态物质、粒子物理学到量子光学等各种物理系统中表现出来的涌现现象。我们研究它们在包含集体物质相互作用的各向异性狄克模型中的行为。我们通过霍尔斯坦 - 普里马科夫变换研究热力学极限下的低能谱，并将结果与通过相干态获得的半经典能量曲面进行对比。我们还探索了参数空间中玻色子和自旋轮廓的几何相位作为系统中相位的函数。由于各向异性与物质相互作用之间的相互作用所提供的独特临界特征，我们揭示了新现象。我们期望我们的结果有助于在当前量子信息平台中观测相位和振幅模式。
