Bethe Ansatz solution of the small polaron with nondiagonal boundary terms
Nikos Karaiskos, André M. Grabinski, Holger Frahm
The small polaron with generic, nondiagonal boundary terms is investigated within the framework of quantum integrability. The fusion hierarchy of the transfer matrices and its trun…

Truncation identities for the small polaron fusion hierarchy
André M. Grabinski, Holger Frahm
We study a one-dimensional lattice model of interacting spinless fermions. This model is integrable for both periodic and open boundary conditions, the latter case includes the pre…

Non-diagonal boundary conditions for gl(1|1) super spin chains
André M. Grabinski, Holger Frahm
We study a one-dimensional model of free fermions with supersymmetry and demonstrate how non-diagonal boundary conditions can be incorporated into the framewor…
