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…
An integrable Anderson-impurity problem embedded in the one-dimensional Hubbard model
Renjie Song, Mingchen Zheng, Junpeng Cao +1
An exactly solvable one-dimensional Hubbard model with a single Anderson impurity embedded at the boundary is constructed in the framework of the quantum inverse scattering method.…
Exact spin helix eigenstates in the anisotropic spin- Heisenberg model with arbitrary dimensions
Mingchen Zheng, Chenguang Liang, Shu Chen +1
Spin helix states-characterized by their spatially modulated spin textures-are exact eigenstates of the one-dimensional anisotropic spin- Heisenberg model under specif…
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…
