Abstract

We find the long-wave asymptotics of the equal time field correlator (one-particle density matrix) in the one-dimensional system of spin 1 2 particles with strong repulsion. At zero temperature the correlator decreases as a power of the distance, the critical exponent being expressed in terms of the velocity of charge excitations.
