论文摘要
与微波腔($ LC $ resonators)耦合的磁分子系统进行了平衡的超级相位过渡。过渡是可以观察到的。首先,通过量子模型中真空诱导的铁磁顺序来说明耦合的效果,然后通过修改$ {\ rm fe_8} $偶性晶体的磁相图的修改,例证了内在的和光子诱导的自旋型旋转相互作用之间的合作。最后,显示了一个传输实验可以解析过渡,从而测量了磁性的量子电动力控制。
A system of magnetic molecules coupled to microwave cavities ($LC$ resonators) undergoes the equilibrium superradiant phase transition. The transition is experimentally observable. The effect of the coupling is first illustrated by the vacuum-induced ferromagnetic order in a quantum Ising model and then by the modification of the magnetic phase diagram of ${\rm Fe_8}$ dipolar crystals, exemplifying the cooperation between intrinsic and photon-induced spin-spin interactions. Finally, a transmission experiment is shown to resolve the transition, measuring the quantum electrodynamical control of magnetism.
