Non-conservation of the valley density and its implications for the observation of the valley Hall effect
Alexander Kazantsev, Amelia Mills, Eoin O'Neill +3
We show that the conservation of the valley density in multivalley insulators is broken in an unexpected way by the electric field that drives the valley Hall effect. This implies…
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…
Observation of Majorana fermions with spin selective Andreev reflection in the vortex of topological superconductor
Hao-Hua Sun, Kai-Wen Zhang, Lun-Hui Hu +14
Majorana fermion (MF) whose antiparticle is itself has been predicted in condensed matter systems. Signatures of the MFs have been reported as zero energy modes in various systems.…
