- Abstract: Nanoscale quantum dots in microwave cavities can be used as a laboratory for
exploring electron-electron interactions and their spin in the presence of
quantized light and a magnetic field. We show how a simple theoretical model of
this interplay at resonance predicts complex but measurable effects. New
polariton states emerge that combine spin, relative modes, and radiation. These
states have intricate spin-space correlations and undergo polariton transitions
controlled by the microwave cavity field. We uncover novel topological effects
involving highly correlated spin and charge density that display
singlet-triplet and inhomogeneous Bell-state distributions. Signatures of these
transitions are imprinted in the photon distribution, which will allow for
optical read-out protocols in future experiments and nanoscale quantum
technologies.

In cavity quantum electrodynamics (QED), emitters and a resonator are coupled together to enable precise studies of quantum light-matter interactions.
Here we provide an observation of the continuous superradiant phase transition predicted in the CRF model using an ensemble of ultracold $88$Sr atoms.
Our observations are a first step towards finer control of driven-dissipative systems, which have been predicted to generate quantum states.

In "loop-coupled" systems, where there are at least as many couplings as modes, the coupling phases become relevant for the physics.
