Generalized spin kitten states in a strongly coupled spin-oscillator system

Utilizing an adiabatic approximation method, a bipartite qudit-oscillator Hamiltonian is studied for low-spin values in both strong and ultrastrong coupling regimes. The quasiprobability densities on the hybrid factorized phase space are introduced. Integrating over sector of composite space, distributions its complementary subsystem recovered. In regime, qudit entropy displays pattern quasiperiodic collapses revivals, where latter coincide with locally minimum configurations. Starting factorizable initial state, we observe that almost pure spin kitten type states dynamically develop at near-null entropy. Hilbert-Schmidt distance measure these puts them metrically far away from state. Other localized form but significantly large evolution to nonclassical transitory displayed via diagonal ${\mathrm{P}}_{\mathcal{Q}}$ representation. As another manifestation nonclassicality emergence spin-squeezed during observed. domain, number interaction-dependent modes their harmonics generated. consequent randomization phases eliminates quasiperiodicity system which now driven towards stabilization also undergoes stochastic fluctuations around suitably stabilized value. realms, antibunching photoemission events realized particularly small values.
