Exact solutions of hidden free fermion models
Mingchen Zheng, Balázs Pozsgay, Shu Chen
Hidden-free-fermion (HFF) Hamiltonians exhibit free-fermion spectra despite lacking an explicit quadratic representation, yet their algebraic provenance and periodic-boundary behav…

Exact solution of a two-parameter extended Bariev model
Mingchen Zheng, Xin Zhang, Junpeng Cao +2
An exactly solvable strongly correlated electron model with two independent parameters is constructed in the frame of the quantum inverse scattering method, which can be seen as a…

Exact solution of the Bose Hubbard model with unidirectional hopping
Mingchen Zheng, Yi Qiao, Yupeng Wang +2
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 mode…
