Asymptotic form of the two-point correlation function of theXXZspin chain

Yasuhiro Fujii, Miki Wadati

Correlation functions of the XXZ spin chain in the critical regime are studied at zero temperature. They are exactly represented in the Fredholm determinant form and are related to an operator-valued Riemann-Hilbert problem. Analysing this problem we prove that a two-point correlation function is asymptotically expressed in terms of power functions of the distance between spin operators.

Long-time large-distance asymptotics of the transverse correlation functions of the XX chain in the spacelike regime

Frank Göhmann, Karol Kajetan Kozlowski, Junji Suzuki

Abstract We derive an explicit expression for the leading term in the long-time, large-distance asymptotic expansion of a transverse dynamical two-point function of the XX chain in the spacelike regime. This expression is valid for all nonzero finite temperatures and for all magnetic fields below the saturation threshold. It is obtained here by means of a straightforward term-by-term analysis of a thermal form factor series, derived in previous work, and demonstrates the usefulness of the latter.
