Critical Phases of the extended isotropic chain with four-spin interaction
Nika Kurdadze, Giorgi Gogaberishvili, G. I. Japaridze
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…
Orbital antiferromagnetic currents in a frustrated fermionic ladder
Shota Garuchava, G. I. Japaridze, A. A. Nersesyan
We consider a spinless - ionic Hubbard chain at 1/2 filling and large hopping ratio . In this limit the model adequately maps onto a weakly coupled triangular ladder w…
Repulsion driven metallic phase in the ground state of the half-filled ionic Hubbard chain
Gerardo L. Rossini, George I. Japaridze
An unusual metallic phase is proven to develop in the one dimensional ionic Hubbard model, at half-filling and zero magnetization, at intermediate electron-electron repulsion w…
Mean-field ground-state phase diagram of the ionic-Hubbard chain
Mikheil Sekania, Shota Garuchava, Jamal Berakdar +1
Ground state (GS) phase diagram of the one dimensional repulsive Hubbard model with both nearest neighbor () and next-nearest-neighbor () hopping and a staggered pot…
Novel Outlook on the Eigenvalue Problem for the Orbital Angular Momentum Operator
George Japaridze, Anzor Khelashvili, Koba Turashvili
Based on the novel prescription for the power of a complex number, a new expression for the eigenfunction of the operator of the third component of the angular momentum is presente…
