Spin conductivity of the XXZ chain in the antiferromagnetic massive regime
Frank Göhmann, Karol K. Kozlowski, Jesko Sirker +1
We present a series representation for the dynamical two-point function of the local spin current for the XXZ chain in the antiferromagnetic massive regime at zero temperature. Fro…
Exact real-time longitudinal correlation functions of the massive XXZ chain
Constantin Babenko, Frank Göhmann, Karol K. Kozlowski +2
We apply the recently developed thermal form factor expansion method to evaluate the real-time longitudinal spin-spin correlation functions of the spin- XXZ chain in t…
A thermal form factor series for the longitudinal two-point function of the Heisenberg-Ising chain in the antiferromagnetic massive regime
Constantin Babenko, Frank Göhmann, Karol K. Kozlowski +1
We consider the longitudinal dynamical two-point function of the XXZ quantum spin chain in the antiferromagnetic massive regime. It has a series representation based on the form fa…
Late-time large-distance asymptotics of the transverse correlation functions of the XX chain in the space-like regime
Frank Göhmann, Karol K. Kozlowski, Junji Suzuki
We derive an explicit expression for the leading term in the late-time, large-distance asymptotic expansion of a transverse dynamical two-point function of the XX chain in the spac…
Equilibrium dynamics of the XX chain
Frank Göhmann, Karol K. Kozlowski, Jesko Sirker +1
The equilibrium dynamics of the spin-1/2 XX chain is re-examined within a recently developed formalism based on the quantum transfer matrix and a thermal form factor expansion. The…
High-temperature analysis of the transverse dynamical two-point correlation function of the XX quantum-spin chain
Frank Göhmann, Karol K. Kozlowski, Junji Suzuki
We analyse the transverse dynamical two-point correlation function of the XX chain by means of a thermal form factor series. The series is rewritten in terms of the resolvent and t…
