Algebraic Bethe ansatz for the one-dimensional Hubbard model with open boundaries

The one-dimensional Hubbard model with open boundary conditions is exactly solved by means of the algebraic Bethe ansatz. The eigenvalue of the transfer matrix and the energy spectrum, as well as the Bethe ansatz equations, are obtained.

Exact solution of a generalized two-sites Bose-Hubbard model

Gilberto N. Santos Filho

I introduce a new parametrization of a bosonic Lax operator for the algebraic Bethe ansatz method with the $gl(2)$-invariant $R$-matrix and use it to present the exact solution of a generalized two-sites Bose-Hubbard model with asymmetric tunnelling. In the no interaction limit I show that the Bethe ansatz equations can be written as a $S^{N-1}$ sphere, where $N$ is the total number of atoms in the condensate.

Bethe ansatz solutions of the 1D extended Hubbard-model

Haiyang Hou, Pei Sun, Yi Qiao +3 more

Abstract We construct an integrable 1D extended Hubbard model within the framework of the quantum inverse scattering method. With the help of the nested algebraic Bethe ansatz method, the eigenvalue Hamiltonian problem is solved by a set of Bethe ansatz equations, whose solutions are supposed to give the correct energy spectrum.

Exact Solution of the Bose-Hubbard Model with Unidirectional Hopping

Mingchen Zheng, Yi Qiao, Yupeng Wang +2 more

A one-dimensional Bose-Hubbard model with unidirectional hopping is shown to be exactly solvable. Applying the algebraic Bethe ansatz method, we prove the integrability of the model and derive the Bethe ansatz equations. The exact eigenvalue spectrum can be obtained by solving these equations. The distribution of Bethe roots reveals the presence of a superfluid-Mott insulator transition at the ground state, and the critical point is determined. By adjusting the boundary parameter, we demonstrate the existence of a non-Hermitian skin effect even in the presence of interaction, but it is completely suppressed for the Mott insulator state in the thermodynamical limit. Our result represents a new class of exactly solvable non-Hermitian many-body systems, which has no Hermitian correspondence and can be used as a benchmark for various numerical techniques developed for non-Hermitian many-body systems.

I introduce a new parametrization of a bosonic Lax operator for the algebraic Bethe ansatz method with the gl(2)gl(2)gl(2)-invariant RRR-matrix and use it to present the exact solution of a generalized two-sites Bose-Hubbard model with asymmetric tunnelling. In the no interaction limit I show that the Bethe ansatz equations can be written as a SN−1S^{N-1}SN−1 sphere, where NNN is the total number of atoms in the condensate.
