Critical Phases of the extended isotropic chain with four-spin interaction
Nika Kurdadze, Giorgi Gogaberishvili, Giorgi Gogabedashvili +1
Using the Jordan-Wigner transformation we calculate exactly the ground state and low-temperature thermodynamic properties of the spin isotropic chain with four spin in…

The large expansion for a half-filled asymmetric Hubbard model on a triangular ladder in the presence of spin-dependent magnetic flux
Shota Garuchava, Bachana Beradze, Tatia Sharia +1
We consider a half-filled system of spin-1/2 fermions on a triangular ladder with spin-dependent hopping in the presence of spin-dependent flux. Using the Schrieffer-Wolff transfor…
