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…
