Perfect elliptic dichroism: Probing the metric of anisotropic quantum Hall droplets
Bruno Mera, Alberto Nardin, Anaïs Defossez +3
Understanding the geometry of quantum Hall systems is a central challenge in modern condensed matter physics. We introduce a framework for probing the geometric structure of quantu…
Hall viscosity from metric-sensitive dichroic probes
Alberto Nardin, Bruno Mera, Anaïs Defossez +3
Hall viscosity characterizes the geometric response of a quantum Hall droplet to deformations of the underlying metric, yet it has remained difficult to measure directly. We propos…
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…
Electrostatics-induced breakdown of the integer quantum Hall effect in cavity QED
Gian Marcello Andolina, Zeno Bacciconi, Alberto Nardin +3
We address the prevailing theoretical explanation of the recently observed breakdown of the integer quantum Hall effect in a two-dimensional electron gas embedded in a metallic spl…
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.…
Circular Dichroism on the Edge of Quantum Hall Systems: From Many-Body Chern Number to Anisotropy Measurements
F. Nur Ünal, A. Nardin, N. Goldman
Quantum Hall states are characterized by a topological invariant, the many-body Chern number, which determines their quantized Hall conductivity. This invariant also emerges in cir…
Universality and two-body losses: lessons from the effective non-Hermitian dynamics of two particles
Alice Marché, Hironobu Yoshida, Alberto Nardin +2
We study the late-time dynamics of two particles confined in one spatial dimension and subject to two-body losses. The dynamics is exactly described by a non-Hermitian Hamiltonian…
Quantum nonlinear optics on the edge of a few-particle fractional quantum Hall fluid in a small lattice
Alberto Nardin, Daniele De Bernardis, Rifat Onur Umucalilar +3
We study the quantum dynamics in response to time-dependent external potentials of the edge modes of a small fractional quantum Hall fluid composed of few particles on a lattice in…
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…
Laughlin's quasielectron as a non-local composite fermion
Alberto Nardin, Leonardo Mazza
We discuss the link between the quasielectron wavefunctions proposed by Laughlin and by Jain and show both analytically and numerically that Laughlin's quasielectron is a non-local…
Refermionized theory of the edge modes of a fractional quantum Hall cloud

Making use of refermionization techniques, we map the nonlinear chiral Luttinger liquid model of the edge modes of a spatially confined fractional quantum Hall cloud developed in o…

We prove a generic spin-statistics relation for the fractional quasiparticles that appear in abelian quantum Hall states on the disk. The proof is based on an efficient way for com…
