On the six-vertex model's free energy
Hugo Duminil-Copin, Karol Kajetan Kozlowski, Dmitry Krachun +2
In this paper, we provide new proofs of the existence and the condensation of Bethe roots for the Bethe Ansatz equation associated with the six-vertex model with periodic boundary…
Rotational invariance in critical planar lattice models
Hugo Duminil-Copin, Karol Kajetan Kozlowski, Dmitry Krachun +2
We prove that the large-scale properties of a number of two-dimensional lattice models are rotationally invariant. More precisely, we prove that the random-cluster model on the squ…
Exact real-time longitudinal correlation functions of the massive XXZ chain
Constantin Babenko, Frank Göhmann, Karol K. Kozlowski +2
We apply the recently developed thermal form factor expansion method to evaluate the real-time longitudinal spin-spin correlation functions of the spin- XXZ chain in t…
A thermal form factor series for the longitudinal two-point function of the Heisenberg-Ising chain in the antiferromagnetic massive regime
Constantin Babenko, Frank Göhmann, Karol K. Kozlowski +1
We consider the longitudinal dynamical two-point function of the XXZ quantum spin chain in the antiferromagnetic massive regime. It has a series representation based on the form fa…
Large deviations of energy transfers in nonequilibrium CFT and asymptotics of non-local Riemann-Hilbert problems
Krzysztof Gawedzki, Karol K. Kozlowski
A wide class of dimensional unitary conformal field theories allows for an explicit construction of nonequilibrium "profile states" interpolating smoothly between different e…
On convergence of form factor expansions in the infinite volume quantum Sinh-Gordon model in 1+1 dimensions
K. K. Kozlowski
This paper develops a technique allowing one to prove the convergence of a class of series of multiple integrals which corresponds to the form factor expansion of two-point functio…
