arXiv:cond-mat/9404062 · doi:10.1103/PhysRevLett.73.332

Abstract

Highly accurate results are presented for the susceptibility, of the Heisenberg antiferromagnetic chain for all temperatures, using the Bethe ansatz and field theory methods. After going through a rounded peak, approaches its asympotic zero-temperature value with infinite slope.
