摘要：

The hysteretic response of an Ising system to a periodically varying transverse (tunnelling) field has been investigated. Numerical and approximate analytical techniques have been used to solve the mean-field equation for the dynamics, in the presence of a heat bath at a finite temperature. The scaling behaviour of the hysteresis loop area and the phase diagram for the dynamic (phase) transition have been obtained.
