Integrable domain walls in ABJM theory
Charlotte Kristjansen, Dinh-Long Vu, Konstantin Zarembo
One-point functions of local operators are studied, at weak and strong coupling, for the ABJM theory in the presence of a 1/2 BPS domain wall. In the underlying quantum spin chain…
A diagrammatic approach towards the thermodynamics of integrable systems
Dinh-Long Vu
We propose an exact summation method to compute thermodynamic observables in integrable quantum field theories. The key idea is to use the matrix-tree theorem to write the Gaudin d…
Boundary entropy of integrable perturbed WZNW
Ivan Kostov, Didina Serban, Dinh-Long Vu
We apply the recently developped analytical methods for computing the boundary entropy, or the g-function, in integrable theories with non-diagonal scattering. We consider the part…
Boundary TBA, trees and loops
Ivan Kostov, Didina Serban, Dinh-Long Vu
We derive a graph expansion for the thermal partition function of solvable two-dimensional models with boundaries. This expansion of the integration measure over the virtual partic…
TBA and tree expansion
Ivan Kostov, Didina Serban, Dinh-Long Vu
We propose an alternative, statistical, derivation of the Thermodynamic Bethe Ansatz based on the tree expansion of the Gaudin determinant. We illustrate the method on the simplest…
