Critical bifurcation and deconfined quantum criticality in an interacting cluster Ising chain
Sourabh, Bachana Beradze, Mikheil Tsitsishvili +2
We investigate the cluster Ising chain with an additional nearest-neighbor interaction using tensor-network methods and a weak-coupling field theory. Without the interaction, the J…

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…
