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…

Emergent superconformal symmetry in the phase diagram of a 1D lattice gauge theory
Bachana Beradze, Mikheil Tsitsishvili, Sergej Moroz
We investigate the phase diagram and critical properties of a one-dimensional lattice gauge theory describing an orthogonal metal, where spinless fermions and Isin…

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…
