摘要: A transverse Ising spin system, in the presence of time-dependent longitudinal field, is studied by effective-field theory (EFT). The equations motion average magnetization are given for simple cubic lattice (Z = 6) and honeycomb 3). Liapunov exponent lambda calculated discussing stability it used to determine phase boundary. dynamic transition diagrams h(0)/ZJ -Gamma/ZJ plane - T/ZJ have been drawn, there no dynamical tricritical point on effect thermal fluctuations upon boundary has discussed
