We present a graphene derivative displaying novel topological phenomena without the spin-orbit coupling (SOC) in a collinear altermagnet. By investigating the retarded and advanced Green's functions, we calculate the spectral density and amplitude of

The discovery of high-temperature superconductivity (HTSC) in pressurized La$_3$Ni$_2$O$_7$ has aroused a surge in the exploration of HTSC in the multilayer nickelates. Presently, while HTSC is only found in pressurized circumstance, most of the expe

Controlling magnetic anisotropy energy (MAE) in two-dimensional (2D) ferromagnetic materials is crucial for designing novel spintronic devices. Using first-principles calculations, we systematically investigate the magnetic properties of monolayer Fe

Magnon Chern insulators (MCIs) exhibit unique topological magnon band structures featuring chiral edge states. Direct observations of the topologically protected magnon edge states have long been pursued. Here, we report the spatially resolved detect

The Einstein-de Haas (EdH) effect is an interesting phenomenon linking mechanics and magnetism, in which changes in magnetization induce mechanical rotation. Despite being discovered more than a century ago, the EdH effect still shows crucial signifi

Motivated by the discovery of high-temperature superconductivity in bilayer nickelate La$_3$Ni$_2$O$_7$ under pressure, we investigate the ground-state phase diagram and correlation effects using determinant quantum Monte Carlo simulations in a simpl
