Employing large-scale quantum Monte Carlo simulations, we find in magnetized interacting Dirac fermion model, there emerges a new and universal collective Larmor-Silin spin wave mode in the transverse dynamical spin susceptibility. Such mode purely o

Employing large-scale quantum Monte Carlo simulations, we systematically compute the energy spectra of the 2D spin-1/2 Heisenberg model with long-range interactions. With the $1/r^{\alpha}$ ferromagnetic and staggered antiferromagnetic interactions,

Similar to Weyl semimetals, in magnetic materials, magnon bands can host Weyl points, around which the bosonic excitations are called Weyl magnons. Here, we investigate the Klein tunneling of Weyl magnons, during the process of which Weyl magnons tun
