Spin incoherent liquid and interaction-driven criticality in 1D Hubbard model
Jia-Jia Luo, Han Pu, Xi-Wen Guan
Although the one dimensional (1D) repulsive Fermi-Hubbard model has been intensively studied over many decades, a rigorous understanding of many aspects of the model is still lacki…
Excitation Spectra of one-dimensional spin-1/2 Fermi gas with an attraction
Jia-Feng Pan, Jia-Jia Luo, Xi-Wen Guan
Using exact Bethe ansatz solution, we rigorously study excitation spectra of the spin-1/2 Fermi gas (called Yang-Gaudin model) with an attractive interaction. Elementary excitation…
