Boundary overlap in the open XXZ spin chain
Charbel Abetian, Nikolai Kitanine, Veronique Terras
In this paper we compute the overlaps of the ground states for the open spin chains after a change of one of the boundary magnetic fields. It can be considered as the first step to…

Fredholm Determinants from Schrödinger Type Equations, and Deformation of Tracy-Widom Distribution
Taro Kimura, Xavier Navand
We undertake an analysis of Fredholm determinants arising from kernels whose defining functions satisfy a Schrödinger type equation. When this defining function is the Airy one, th…

Equality of magnetization and edge current for interacting lattice fermions at positive temperature
Jonas Lampart, Massimo Moscolari, Stefan Teufel +1
We prove that the magnetization is equal to the edge current in the thermodynamic limit for a large class of models of lattice fermions with finite-range interactions satisfying lo…
