Ground states of the Ising model at fixed magnetization on a triangular ladder with three-spin interactions
Shota Garuchava
We study the Ising model at fixed magnetization on a triangular ladder with three-spin interactions. By recasting the ground-state determination as a linear programming (LP) proble…
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…
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…
