Quasi-classical expansion of a hyperbolic solution to the star-star relation and multicomponent 5-point difference equations
Andrew P. Kels
The quasi-classical expansion of a multicomponent spin solution of the star-star relation with hyperbolic Boltzmann weights is investigated. The equations obtained in a quasi-class…
Algebraic entropy for hex systems
Giorgio Gubbiotti, Andrew P. Kels, Claude-M. Viallet
Hex systems were recently introduced [A. P. Kels. Integrable systems on hexagonal lattices and consistency on polytopes with quadrilateral and hexagonal faces. 2022. arXiv:2205.027…
Integrable systems on hexagonal lattices and consistency on polytopes with quadrilateral and hexagonal faces
Andrew P. Kels
The new concept of a system of hex equations is introduced as an overdetermined system of six five-point face-centered quad equations defined on six vertices of a hexagon. For a co…
Discrete integrable equations on face-centered cubics: consistency and Lax pairs of corner equations
Andrew P. Kels
A new set of discrete integrable equations, called face-centered quad equations, was recently obtained using new types of interaction-round-a-face solutions of the classical Yang-B…
Algebraic entropy for face-centered quad equations
Giorgio Gubbiotti, Andrew P. Kels
In this paper we define the algebraic entropy test for face-centered quad equations, which are equations defined on vertices of a quadrilateral plus an additional interior vertex.…
Entanglement of two disjoint intervals in conformal field theory and the 2D Coulomb gas on a lattice
Tamara Grava, Andrew P. Kels, Erik Tonni
In the conformal field theories given by the Ising and Dirac models, when the system is in the ground state, the moments of the reduced density matrix of two disjoint intervals and…
