Asymptotic analysis of a Fredholm determinant occurring in the description of the dynamical correlation functions of the Lieb--Liniger Bose gas
Frank Göhmann, Karol K. Kozlowski, Mikhail D. Minin
We perform a large- asymptotic analysis of the Fredholm determinant of an integrable integral operator with generalized sine kernel, where controls the strength of the oscil…
Decay of spin helices in XXZ quantum spin chains with single-ion anisotropy
Florian Lange, Frank Göhmann, Gerhard Wellein +1
Long-lived spin-helix states facilitate the study of non-equilibrium dynamics in quantum magnets. We consider the decay of transverse spin-helices in antiferromagnetic spin- XXZ…
Ballistic particle transport and Drude weight in gases
Frank Göhmann, Andreas Klümper, Karol K. Kozlowski
Owing to the fact that the particle current operator in non-relativistic gases is proportional to the total momentum operator, the particle transport in such systems is always ball…
Chiral eigenbases of the XX and XY quantum spin chains
Xin Zhang, Frank Göhmann, Andreas Klümper +1
We calculate the values of observables in chiral eigenstates of the XX quantum spin chain that were introduced in previous work and compare the form of the result with the respecti…
Space-like asymptotics of the thermal two-point functions of the XXZ spin-1/2 chain
F. Göhmann, K. K. Kozlowski
This work proposes a closed formula for the leading term of the long-distance and large-time asymptotics in a cone of the space-like regime for the transverse dynamical two-point f…
Bethe Ansatz
Frank Göhmann
The term Bethe Ansatz stands for a multitude of methods in the theory of integrable models in statistical mechanics and quantum field theory that were designed to study the spectra…
