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.…
Edge dynamics of an Integer Quantum Hall system
Alberto Nardin
In this master thesis work the linear and non linear edge dynamics of a non-interacting system of fermions in a Integer Quantum Hall state is theoretically and numerically studied.
