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…
Emergence of non-Abelian SU(2) invariance in Abelian frustrated fermionic ladders
Bachana Beradze, Mikheil Tsitsishvili, Emanuele Tirrito +3
We consider a system of interacting spinless fermions on a two-leg triangular ladder with magnetic flux per triangular plaquette. Microscopically, the system exhibits a U(1)…
