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…
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…
Topological entanglement properties of disconnected partitions in the Su-Schrieffer-Heeger model
Tommaso Micallo, Vittorio Vitale, Marcello Dalmonte +1
We study the disconnected entanglement entropy, , of the Su-Schrieffer-Heeger model. is a combination of both connected and disconnected bipartite entanglement entropies…
Lattice Bisognano-Wichmann modular Hamiltonian in critical quantum spin chains
Jiaju Zhang, Pasquale Calabrese, Marcello Dalmonte +1
We carry out a comprehensive comparison between the exact modular Hamiltonian and the lattice version of the Bisognano-Wichmann (BW) one in one-dimensional critical quantum spin ch…
