摘要: We have studied an Ising spin system in a transverse field, at zero temperature, under time oscillating longitudinal field by means of mean-field approximation and Monte Carlo algorithm, appropriate to study the ground-state properties quantum chains. For large values Γ or amplitude h0 magnetization oscillates around value with same frequency but delayed. Decreasing Γ, small h0, undergoes phase transition state which nonzero value. also obtained behavior hysteresis loop area near Curie point.
