Asymptotic analysis of the dynamical field-field correlation function of the impenetrable Bose gas
Frank Göhmann, Karol K. Kozlowski, Mikhail D. Minin +1
We study the long-time, large-distance asymptotic behaviour of the two-point correlation function of fields of the impenetrable Bose gas in equilibrium states characterized by a qu…

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…
