Exact SU() symmetry resolution of bosonic Hubbard models: general boson-fermion mappings and flat-band singlet-cluster states

Loïc Herviou

We show how to perform exact diagonalization of SU()-symmetric Bose-Hubbard models separately in each irreducible representation of SU(), by exploiting the Howe duality betwe…

Finite-state automata for exact matrix product operators of tight-binding Hamiltonians: fractals, quasicrystals, trees and hyperbolic lattices

Marta Brzezińska, Jeanne Colbois, Loïc Herviou

Inspired by the recent progress in the simulation of tight-binding Hamiltonians on large lattices using tensor networks, we introduce a systematic matrix product operator (MPO) con…

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…

Why finite-size non-Hermitian eigenvalues can miss asymptotic eigenstates in topological physics

Lucien Jezequel, Loïc Herviou, Jens H. Bardarson +1

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…
