“…which resemble the bosonized Hamiltonian for the undriven LMG model [35,36], in this case, however, the Hamiltonian is characterized by a time dependent squeezing parameter [23]. Previous works have used the Holstein-Primakoff transformation to study the finitesize exponents in the LMG model [35], entanglement measurements in fully connected spin models [36], and to investigate collective spin systems at high temperatures [37]. By introducing the coordinate operators in Eq.…”

We establish a set of nonequilibrium quantum phase transitions in the Lipkin-Meshkov-Glick model under monochromatic modulation of the interparticle interaction. We show that the external driving induces a rich phase diagram that characterizes the multistability in the system. Interestingly, the number of stable configurations can be tuned by increasing the amplitude of the driving field. Furthermore, by studying the quantum evolution, we demonstrate that the system exhibits a set of quantum phases that correspond to dynamically stabilized states.

We show that the probability distribution corresponding to a fully random tracial state of a system of spin-S particles satisfies a diffusion-like equation. The diffusion coefficient turns out to be equal to $S(S+1)/6$, where $S$ is the magnitude of the spin of each particle. We also introduce a bosonization scheme for the lowering and raising operators.Comment: 3 pages,typos fixed, now the discussion includes some remarks on the bosonizatio

Abstract: We report on a nontrivial bosonization scheme for spin operators. It is shown that in the large N limit, at infinite temperature, the operators
