论文摘要
获得了与显示三维周期轮廓的空腔模式的原子的特征状态的形式。结果表明，量化的运动导致否定了原子自由度的堕落状态，也就是说，在发现该复合系统的一个组成部分后，其他人仍然处于纠缠状态。当系统扩展到包括驱动器和耗散时，发现在临界驱动振幅下会发生耗散量子相变。与文献中报道的其他相变不同，堕落性在检测到电磁场后，在不兼容状态的叠加中制备了该系统。探测该场在过渡点以上的阶数中提示，该阶面由于状态掩盖，使原子相干性在长时间生存。
The form of the eigenstates of an atom coupled to a cavity mode displaying a three dimensional periodic profile are obtained. It is shown that the quantized motion leads to degenerate states where the atomic degrees of freedom are masked, that is, upon detection of one component of this composite system the others remain in an entangled state. When the system is extended to include drive and dissipation it is found to undergo a dissipative quantum phase transition at a critical drive amplitude. Unlike other phase transitions reported in the literature, the degeneracy prepares the system in a superposition of incompatible states upon detection of the electromagnetic field. Probing the field hints at an order above the transition point that, due to state masking, allows for atomic coherence to survive at long times.
