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…
Information transport and transport-induced entanglement in open fermion chains
Andrea Nava, Claudia Artiaco, Yuval Gefen +4
Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin…
From Kardar-Parisi-Zhang scaling to soliton proliferation in Josephson junction arrays
Mikheil Tsitsishvili, Reinhold Egger, Karsten Flensberg +1
We propose Josephson junction arrays as realistic platforms for observing nonequilibrium scaling laws characterizing the Kardar-Parisi-Zhang (KPZ) universality class, and space-tim…
Entanglement enhancement induced by noise in inhomogeneously monitored systems
Cristiano Muzzi, Mikheil Tsitsishvili, Giuliano Chiriacò
We study how stronger noise can enhance the entanglement in inhomogeneously monitored quantum systems. We consider a free fermions model composed of two coupled chains - a system c…
Measurement induced transitions in non-Markovian free fermion ladders
Mikheil Tsitsishvili, Dario Poletti, Marcello Dalmonte +1
Recently there has been an intense effort to understand measurement induced transitions, but we still lack a good understanding of non-Markovian effects on these phenomena. To that…
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)…
Diagrammatic method for many-body non-Markovian dynamics: memory effects and entanglement transitions
Giuliano Chiriacò, Mikheil Tsitsishvili, Dario Poletti +2
We study the quantum dynamics of a many-body system subject to coherent evolution and coupled to a non-Markovian bath. We propose a technique to unravel the non-Markovian dynamics…
Phase diagram of Rydberg-dressed atoms on two-leg triangular ladders
Pierre Fromholz, Mikheil Tsitsishvili, Matteo Votto +3
Dressed Rydberg atoms in optical lattices are a promising platform for the quantum simulation of intriguing phenomena emerging in strongly interacting systems. Relevant to such a s…
Phase diagram of Rydberg-dressed atoms on two-leg square ladders: Coupling supersymmetric conformal field theories on the lattice
Mikheil Tsitsishvili, Titas Chanda, Matteo Votto +3
We investigate the phase diagram of hard-core bosons in two-leg ladders in the presence of soft-shoulder potentials. We show how the competition between local and non-local terms g…
Edge States of a Periodic Chain with Four-Band Energy Spectrum
M. Eliashvili, D. Kereselidze, G. Tsitsishvili +1
Tight-binding model on a finite chain is studied with four-fold alternated hopping parameters . Imposing the open boundary conditions, the corresponding recursion is s…
