Abstract
Numerical results such as the specific heat, magnetic susceptibility, ground-state energy, and the magnon gap obtained with computer renormalization-group technique are presented for CsNi. No soliton states of the type analogous to the sine-Gordon kink were found. This is supported by analytic calculations of the quantum fluctuations of a winding number operator.
