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…
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)…
Spectrum, Lifshitz transitions and orbital currents in frustrated fermionic ladders with a uniform flux
Bachana Beradze, Alexander Nersesyan
Ultracold Fermi gases with synthetic gauge field represent an excellent platform to study the combined effect of lattice frustration and an effective magnetic flux close to one flu…
Quantum correlations in the spin-1/2 Heisenberg XXZ chain with modulated Dzyaloshinskii-Moriya interaction
F. Khastehdel Fumani, B. Beradze, S. Nemati +2
We study a one-dimensional spin-1/2 XXZ Heisenberg model with alternating Dzyaloshinskii- Moriya interaction, using the numerical Lanczos method. Recently, the ground state (GS) ph…
Magnetic phase diagram of a spin S=1/2 antiferromagnetic two-leg ladder in the presence of modulated along legs Dzyaloshinskii-Moriya interaction
Niko Avalishvili, Bachana Beradze, George I. Japaridze
We study the ground-state magnetic phase diagram of a spin S=1/2 antiferromagnetic two-leg ladder in the presence of period two lattice units modulated, Dzyaloshinskii-Moriya (DM)…
Trions and biexcitons in a nanowire
R. Ya. Kezerashvili, Z. S. Machavariani, B. Beradze +1
A theory of the trion and biexciton in a nanowire (NW) in the framework of the effective-mass model using the Born-Oppenheimer approximation is presented. We consider the formation…
