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…
Chiral Gravitons on the Lattice
Hernan B. Xavier, Zeno Bacciconi, Titas Chanda +2
Chiral graviton modes are elusive excitations arising from the hidden quantum geometry of fractional quantum Hall states. It remains unclear, however, whether this picture extends…
Gapless deconfined phase in a symmetric Hamiltonian created in a cold-atom setup
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We investigate a quasi-two-dimensional system consisting of two species of alkali atoms confined in a specific optical lattice potential [Phys. Rev. A 95, 053608 (2017)]. In the lo…
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)…
Classification and emergence of quantum spin liquids in chiral Rydberg models
Poetri Sonya Tarabunga, Giuliano Giudici, Titas Chanda +1
We investigate the nature of quantum phases arising in chiral interacting Hamiltonians recently realized in Rydberg atom arrays. We classify all possible fermionic chiral spin liqu…
First-order photon condensation in magnetic cavities: A two-leg ladder model
Zeno Bacciconi, Gian Marcello Andolina, Titas Chanda +3
We consider a model of free fermions in a ladder geometry coupled to a nonuniform cavity mode via Peierls substitution. Since the cavity mode generates a magnetic field, no-go theo…
Critical light-matter entanglement at cavity mediated phase transition
Giuliano Chiriacò, Marcello Dalmonte, Titas Chanda
We consider a model of a light-matter system, in which a system of fermions (or bosons) is coupled to a photonic mode that drives a phase transitions in the matter degrees of freed…
Self-organized topological insulator due to cavity-mediated correlated tunneling
Titas Chanda, Rebecca Kraus, Giovanna Morigi +1
Topological materials have potential applications for quantum technologies. Non-interacting topological materials, such as e.g., topological insulators and superconductors, are cla…
