We study the all-to-all Ising model in presence of dissipation and periodic external field. The corresponding Lindblad equation has a time-periodic Liouvillian. dynamics magnetizations is explored by using both mean-field theory numerical simulation at finite number spins. result exhibits transition from response small field amplitude to chaotic large amplitude. Lyapunov exponents are calculated, which supports existence classical phase. However, spins, amplitudes. scaling analysis Floquet...
We solve the fully-connected Ising model in presence of dissipation and time-periodic field, with corresponding Lindblad equation having a Liouvillian. The dynamics magnetizations is studied by using both semiclassical approach numerical simulation help permutation symmetry. shows transition from periodic response for small field amplitude to chaotic large amplitude. trajectory Lyapunov exponents are calculated, which support existence phase. But exact simulation, scaling analysis Floquet...
