Scaling limit of -functions for the invariant inhomogeneous XXZ spin- chain near free fermion point
Gleb A. Kotousov, Sergei L. Lukyanov, Daria A. Shabetnik
At the beginning of the 70's, Baxter introduced a multiparametric generalization of the six-vertex model. This integrable system has been found to exhibit a remarkable variety of c…
Boundary Conditions for the Entanglement Cut in 2D Conformal Field Theories
Ananda Roy, Sergei L. Lukyanov, Hubert Saleur
The entanglement spectra for a subsystem in a spin chain fine-tuned to a quantum-critical point contains signatures of the underlying quantum field theory that governs its low-ener…
Scaling limit of the ground state Bethe roots for the inhomogeneous XXZ spin- chain
Sascha Gehrmann, Gleb A. Kotousov, Sergei L. Lukyanov
It is known that for the Heisenberg XXZ spin- chain in the critical regime, the scaling limit of the vacuum Bethe roots yields an infinite set of numbers that coincide…
On the scaling behaviour of an integrable spin chain with symmetry
Gleb A. Kotousov, Sergei L. Lukyanov
The subject matter of this work is a 1D quantum spin - chain associated with the inhomogeneous six-vertex model possessing an additional symmetry. The mo…
Soliton Confinement in a Quantum Circuit
Ananda Roy, Sergei L. Lukyanov
Confinement of topological excitations into particle-like states - typically associated with theories of elementary particles - are known to occur in condensed matter systems, aris…
ODE/IQFT correspondence for the generalized affine Gaudin model
Gleb A. Kotousov, Sergei L. Lukyanov
An integrable system is introduced, which is a generalization of the quantum affine Gaudin model. Among other things, the Hamiltonians are constructed and their…
