Asymptotic expansion of the partition function for -ensembles with complex potentials
Alice Guionnet, Karol Kozlowski, Alex Little
In this work we establish under certain hypotheses the asymptotic expansion of integrals of the form $$\mathcal{Z}_{N,Γ}[V] \, = \, \int_{Γ^N} \prod_{ a < b}^{N}(z_…
Large-x analysis of an operator valued Riemann-Hilbert problem
A. R. Its, K. K. Kozlowski
The purpose of this paper is to push forward the theory of operator-valued Riemann Hilbert problems and demonstrate their effectiveness in respect to the implementation of a non-li…
Long-distance asymptotic behaviour of multi-point correlation functions in massless quantum models
N. Kitanine, K. K. Kozlowski, J. M. Maillet +1
We provide a microscopic model setting that allows us to readily access to the large-distance asymptotic behaviour of multi-point correlation functions in massless, one-dimensional…
Form factor approach to dynamical correlation functions in critical models
N. Kitanine, K. K. Kozlowski, J. M. Maillet +2
We develop a form factor approach to the study of dynamical correlation functions of quantum integrable models in the critical regime. As an example, we consider the quantum non-li…
Surface free energy of the open XXZ spin-1/2 chain
K. K. Kozlowski, B. Pozsgay
We study the boundary free energy of the XXZ spin-$\tf{1}{2}$ chain subject to diagonal boundary fields. We first show that the representation for its finite Trotter number approxi…
Low- asymptotic expansion of the solution to the Yang-Yang equation
K. K. Kozlowski
We prove that the unique solution to the Yang-Yang equation arising in the context of the thermodynamics of the so-called non-linear Schrödinger model admits a low-temperature expa…
TBA for the Toda chain
K. K. Kozlowski, J. Teschner
We give a direct derivation of a proposal of Nekrasov-Shatashvili concerning the quantization conditions of the Toda chain. The quantization conditions are formulated in terms of s…
