Abstract
Section titled āAbstractāWe propose an efficient scheme for simulating the Lipkin-Meshkov-Glick (LMG)\nmodel with nitrogen-vacancy (NV) center ensembles in diamond magnetically\ncoupled to superconducting coplanar waveguide cavities. With the assistance of\nexternal microwave driving fields, we show that the interaction of the NV spins\ncan be easily controlled, and several types of the LMG model can be realized by\ntuning the different parameters. Under the thermal dynamical limit, the\ndistinct non-equilibrium second order quantum phase transition of the spin\nensemble can be achieved at the critical point. Furthermore, we show that the\nspin squeezed state can be generated by tailoring the LMG Hamiltonian to\npossess the two-axis counter-twisting form in this hybrid quantum system.\n
