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…

Form factors of field exponentials in the 1+1 dimensional Sine-Gordon model
Karol K. Kozlowski, Alex Simon
This work provides explicit expressions, in all sectors of the Fock space: soliton, antisoliton and breather, for the fundamental building blocks -the form factors- of the generali…
