Multi-point correlation functions in the boundary XXZ chain at finite temperature
Karol K. Kozlowski, Véronique Terras
We consider multi-point correlation functions in the open XXZ chain with longitudinal boundary fields and in a uniform external magnetic field. We show that, at finite temperature,…
Quantisation of Kadomtsev-Petviashvili equation
Karol K Kozlowski, Evgeny Sklyanin, Alessandro Torrielli
A quantisation of the KP equation on a cylinder is proposed that is equivalent to an infinite system of non-relativistic one-dimensional bosons carrying masses The H…
Asymptotic behaviour of two-point functions in multi-species models
K. K. Kozlowski, E. Ragoucy
We extract the long-distance asymptotic behaviour of two-point correlation functions in massless quantum integrable models containing multi-species excitations. For such a purpose,…
Aspects of the inverse problem for the Toda chain
K. K. Kozlowski
We generalize Babelon's approach to equations in dual variables so as to be able to treat new types of operators which we build out of the sub-constituents of the model's monodromy…
Combinatorics of generalized Bethe equations
Karol Kozlowski, Evgeny Sklyanin
A generalization of the Bethe ansatz equations is studied, where a scalar two-particle S-matrix has several zeroes and poles in the complex plane, as opposed to the ordinary single…
