Description

Various vacuum expectation values in one-dimensional quantum systems are studied using the finite size effects. The scale dimensions of the main operators in the continuous model of a one-dimensional Bose gas with an interaction of a general type are found. The asymptotics of correlators of some nonlocal operators (disortors) is found for the Heisenberg model of an XXZ antiferromagnet. It is demonstrated how the finite size effect can be used to find the spectrum of scale dimensions in fermion systems
