Critical exponents in completely integrable models of quantum statistical physics
N. M. Bogolyubov, A. G. Izergin, V. E. Korepin
Abstract:
In one-dimensional quantum systems phase transition takes place at zero temperature.
The general formula is obtained and investigated for the critical exponent
describing the power decrease of zero-temperature correlators at long distances. This
formula is valid for a great number of one-dimensional models including the Heisenberg
model. The critical exponent is connected with fractional charge; it can also be
expressed in terms of macroscopic characteristics of a model.
