Quantum magic of strongly correlated fermions the Hubbard dimer
Edoardo Zavatti, Gabriele Bellomia, Massimo Capone
We study the non-stabilizerness (quantum magic) content of the Hubbard dimer, an analytically solvable, yet completely non-trivial, model of strongly correlated fermions. We consid…

Emergence of spin entanglement with the pseudogap onset in the Fermi-Hubbard model
Frederic Bippus, Thomas Chalopin, Gabriele Bellomia +6
Despite decades of intense theoretical and experimental investigation, the two-dimensional Fermi-Hubbard model still resists a complete microscopic understanding. Conventional appr…
