On deforming and breaking integrability
Ysla F. Adans, Marius de Leeuw, Tristan McLoughlin
In this paper we study nearest-neighbour deformations of integrable models. After expanding in the deformation parameter, we identify four possible types of deformations. First the…
Hidden quasi-local charges and Gibbs ensemble in a Lindblad system
Marius de Leeuw, Chiara Paletta, Balázs Pozsgay +1
We consider spin-1/2 chains with external driving that breaks the continuous symmetries of the Hamiltonian. We introduce a family of models described by the Lindblad equation with…
A range three elliptic deformation of the Hubbard model
Marius de Leeuw, Chiara Paletta, Balázs Pozsgay
In this paper we present a new integrable deformation of the Hubbard model. Our deformation gives rise to a range 3 interaction term in the Hamiltonian which does not preserve spin…
The Bethe ansatz for a new integrable open quantum system
Marius de Leeuw, Chiara Paletta
In this paper we apply the nested algebraic Bethe ansatz to compute the eigenvalues and the Bethe equations of the transfer matrix of the new integrable Lindbladian found in [1]. W…
