CORRELATION-FUNCTION OF THE SPIN-1/2 XXX ANTIFERROMAGNET
We consider a special correlation function in the isotropic spin- 1 2 Heisenberg antiferromagnet. It is the probability of finding a ferromagnetic string of (adjacent) spins in the antiferromagnetic ground state. We give two different representations for this correlation function. Both of them are e...
