From weakly to strongly-interacting driven-dissipative bosons in one dimension
Martina Zündel, Loïc Herviou, Léonie Canet +1
We consider a one-dimensional driven-dissipative Bose-Hubbard model subjected to incoherent pump and one- and two-body losses, and analyze it by studying its two-point space-time c…
When and why non-Hermitian eigenvalues miss eigenstates in topological physics
Lucien Jezequel, Loïc Herviou, Jens Bardarson
Non-Hermitian systems exhibit a fundamental spectral dichotomy absent in Hermitian physics: the eigenvalue spectrum and the eigenstate spectrum can deviate significantly in the the…
symmetry breaking in SU(N) Fermi-Hubbard dots at zero and finite temperature
Loïc Herviou, Elodie Campan, Pierre Nataf
We address the SU(N) Fermi-Hubbard model on a chain, with the number of degenerate orbitals, or colors, for each fermion. In the limit of both large number of colors and pa…
Universal Characterization of Quantum Many-Body States through Local Information
Claudia Artiaco, Thomas Klein Kvorning, David Aceituno Chávez +2
We propose a universal framework for classifying quantum states based on their scale-resolved correlation structure. Using the recently introduced information lattice, which provid…
A Model for Topological p-wave Superconducting Wires with Disorder and Interactions
Frederick Del Pozo, Loïc Herviou, Olesia Dmytruk +1
We present a comprehensive theoretical study of interacting and disordered topological phases of coupled Kitaev wires, which may support further realistic applications of Majorana…
