Universal collective Larmor-Silin mode emerging in magnetized correlated Dirac fermions
Chuang Chen, Yuan Da Liao, Chengkang Zhou +3
Employing large-scale quantum Monte Carlo simulations, we find that in the magnetized interacting Dirac fermion model there emerges a universal collective Larmor-Silin spin wave mo…
