Robust spin splitting and fermiology in a layered altermagnet
Alessandro De Vita, Chiara Bigi, Davide Romanin +42
Altermagnetism defies conventional classifications of collinear magnetic phases, standing apart from ferromagnetism and antiferromagnetism with its unique combination of spin-depen…
Non-Perturbative Feats in the Physics of Correlated Antiferromagnets
Matthias Reitner, Lorenzo Del Re, Massimo Capone +1
In the last decades multifaceted manifestations of the breakdown of the self-consistent perturbation theory have been identified for the many-electron problem. Yet, the investigati…
Optically Tunable Spin Transport in Bilayer Altermagnetic Mott Insulators
Niklas Sicheler, Roberto Raimondi, Giorgio Sangiovanni +1
Altermagnets are a novel class of materials that combine antiferromagnetic spin ordering with non-relativistic spin splitting (NRSS) in their band structure, making them promising…
Efficient Fermi-Hubbard model ground-state preparation by coupling to a classical reservoir in the instantaneous-response limit
Zekun He, Lorenzo Del Re, A. F. Kemper +1
Preparing the ground state of the Fermi-Hubbard model is challenging, in part due to the exponentially large Hilbert space, which complicates efficiently finding a path from an ini…
Two-particle self-consistent approach for broken symmetry phases
Lorenzo Del Re
Spontaneous symmetry breaking of interacting fermion systems constitutes a major challenge for many-body theory due to the proliferation of new independent scattering channels once…
