Tuning bulk topological magnon properties with light-induced magnons
Dhiman Bhowmick, Hao Sun, Bo Yang +1
Although theoretical modelling and inelastic neutron scattering measurements have indicated the presence of topological magnon bands in multiple quantum magnets, experiments remain…
Discrete time crystal made of topological edge magnons
Dhiman Bhowmick, Hao Sun, Bo Yang +1
We report the emergence of time-crystalline behavior in the π-Berry phase protected edge states of a Heisenberg ferromagnet in the presence of an external driving field. The magnon…
Interacting topological Dirac magnons
Hao Sun, Dhiman Bhowmick, Bo Yang +1
In this work, we study the magnon-magnon interaction effect in typical honeycomb ferromagnets consisting of van der Waals-bonded stacks of honeycomb layers, e.g., chromium trihalid…
Negative Thermal Hall Conductance in Two-Dimer Shastry-Sutherland Model with π-flux Dirac Triplon
Hao Sun, Pinaki Sengupta, Donguk Nam +1
We introduce an effective 2-dimer tight-binding model for the family of Shastry-Sutherland models with geometrically tunable triplon excitations. The Rashba pseudospin-orbit coupli…
