Abstract: Carbon enjoys a vast number of allotropic forms, each possessing unique properties determined by the lattice structures and bonding characters. Here, based on first-principles calculations, we propose a new three-dimensional carbon allotrope--hC28. We show that… read more here.

DOI: 10.1088/0256-307x/34/7/077501
Abstract: We study the topological properties of magnon excitations in a wide class of three-dimensional (3D) honeycomb lattices with ferromagnetic ground states. It is found that they host nodal ring magnon excitations. These rings locate on… read more here.

DOI: 10.1103/physrevb.104.064305
Abstract: We develop a phonon-magnon interaction model for the two-dimensional honeycomb ferromagnet and calculate the band structure of the hybrid phonon-magnon excitation. When the phonon (either acoustic or optical) energy overlaps with the magnon energy, the… read more here.

DOI: 10.1103/physrevb.107.195302
Abstract: Two-dimensional honeycomb ferromagnets offer the unprecedented opportunity to study interactions between collective modes that in standard bulk ferromagnets do not cross paths. Indeed, they harbor an optical spin-wave branch, i.e. a spin wave which disperses… read more here.
