AbstractRecently, a novel kind of hybrid atom-optomechanical system, consisting of atoms in a lattice coupled to a membrane, has been experimentally realized [A. Vochezer et al., Phys. Rev. Lett. 120, 073602 (2018)], which promises a viable contender in the competitive field of simulating nonequilibrium many-body physics. Here we are motivated to investigate a spinor Bose gas coupled to a vibrational mode of a nanomembrane, focusing on analyzing the role of the spinor degrees of freedom therein. Through an adiabatic elimination of the degrees of freedom of the quantum oscillator, we derive an effective Hamiltonian which reveals a competition between the force localizing the atoms and the membrane displacement. We analyze the dynamical stability of the steady state using the Bogoliubov-de Gennes approach and derive the stationary phase diagram in the parameter space. Then, we investigate the first-order nonequilibrium quantum phase transition (NQPT) from a localized symmetric state of the atom cloud to a shifted symmetry-broken state, characterized by the occurrence of a hysteresis. Moreover we present a detailed analysis of the effects of the spin degree of freedom on NQPT. Our work presents a simple way to study the effects of the spinor degree of freedom on the nonequilibrium nonlinear phenomena that is complementary to ongoing experiments on the hybrid atom-optomechanical system.
