Abstract
In the one-dimensional transverse Ising model, we calculate exactly the time evolution and the admittance of the magnetization and also of the energy near the critical point. The results for the above two quantities are shown to coincide with each other, and are explicitly represented in terms of functions of the inverse static susceptibility. The analyses are made by using the recurrence-relations method developed on the basis of Mori’s continued-fraction representation.Keywords
