Fate of a Fractional Chern Insulator under Nonlocal Interactions in Synthetic Dimensions
Patrick Liam Geraghty, Alberto Nardin, Leonardo Mazza +1
Synthetic dimensions provide a powerful route to engineer topological lattice models in ultracold atomic systems, but they contain intrinsic nonlocal interactions along the synthet…
Open quantum spin chains with non-reciprocity: a theoretical approach based on the time-dependent generalized Gibbs ensemble
Alice Marché, Hironobu Yoshida, Alberto Nardin +2
We study an open quantum spin chain with non-reciprocal dissipation using a theoretical approach known as time-dependent generalized Gibbs ensemble. In the regime of weak dissipati…
Fermi-Hubbard gas with three-body losses: symmetries and dark states
Alice Marché, Alberto Nardin, Hosho Katsura +1
We study an invariant Fermi-Hubbard gas undergoing on-site three-body losses. The model presents eight independent strong symmetries preventing the complete deplet…
Spin fractionalization at the edge of quantum Hall fluids induced by bulk quasiparticles
Alexander Fagerlund, Alberto Nardin, Leonardo Mazza +1
We define a measurable spin for the edge of a lowest Landau level and incompressible fractional quantum Hall state in the presence of an Abelian or non-Abelian bulk quasiparticle.…
Many-Body Open Quantum Systems
Rosario Fazio, Jonathan Keeling, Leonardo Mazza +1
These Lecture Notes discuss the recent theoretical advances in the understanding of open quantum many-body physics in platforms where both dissipative and coherent processes can be…
Bisognano-Wichmann Hamiltonian for the entanglement spectroscopy of fractional quantum Hall states
A. Nardin, R. Lopes, M. Rizzi +2
We study the Bisognano-Wichmann Hamiltonian for fractional quantum Hall states defined on a sphere and explore its relationship with the entanglement Hamiltonian associated to the…
