Thermal form factor approach to the ground-state correlation functions of the XXZ chain in the antiferromagnetic massive regime
Maxime Dugave, Frank Göhmann, Karol K. Kozlowski +1
We use the form factors of the quantum transfer matrix in the zero-temperature limit in order to study the two-point ground-state correlation functions of the XXZ chain in the anti…
Asymptotics of correlation functions of the Heisenberg-Ising chain in the easy-axis regime
Maxime Dugave, Frank Göhmann, Karol K. Kozlowski +1
We analyze the long-time large-distance asymptotics of the longitudinal correlation functions of the Heisenberg-Ising chain in the easy-axis regime. We show that in this regime the…
Low-temperature spectrum of correlation lengths of the XXZ chain in the antiferromagnetic massive regime
Maxime Dugave, Frank Göhmann, Karol K. Kozlowski +1
We consider the spectrum of correlation lengths of the spin- XXZ chain in the antiferromagnetic massive regime. These are given as ratios of eigenvalues of the quantum…
On form-factor expansions for the XXZ chain in the massive regime
M. Dugave, F. Göhmann, K. K. Kozlowski +1
We study the large-volume- limit of form factors of the longitudinal spin operators for the XXZ spin- chain in the massive regime. We find that the individual form factors…
Low-temperature large-distance asymptotics of the transversal two-point functions of the XXZ chain
Maxime Dugave, Frank Göhmann, Karol K. Kozlowski
We derive the low-temperature large-distance asymptotics of the transversal two-point functions of the XXZ chain by summing up the asymptotically dominant terms of their expansion…
Functions Characterizing the Ground State of the XXZ Spin-1/2 Chain in the Thermodynamic Limit
Maxime Dugave, Frank Göhmann, Karol K. Kozlowski
We establish several properties of the solutions to the linear integral equations describing the infinite volume properties of the XXZ spin-1/2 chain in the disordered regime. In p…
