Effect of hole-strain coupling on the eigenmodes of semiconductor-based nanomechanical systems
Ankang Liu, Mark Dykman
Electron-phonon coupling can strongly affect the eigenmodes of nano- and micromechanical resonators. We study the effect of the coupling for -doped semiconductor resonators. We…
Spin-wave dynamics controlled by tunable ac magnonic crystal
Ankang Liu, Alexander M. Finkel'stein
The magnonic crystal, which has a spatial modulation wave vector , couples the spin wave with wave vector to the one with wave vector . For a conventional magnonic crys…
Spin waves in layered antiferromagnets with honeycomb structure
Ankang Liu, Alexander M. Finkel'stein
We develop a description of spin waves in a quantum antiferromagnet (AFM) in terms of macroscopic variables, magnetization and Néel vector densities. We consider a layere…
Control of spin waves by spatially modulated strain
Ankang Liu, Alexander M. Finkel'stein
We suggest using spatially modulated strain for control of a spin wave propagating inside a bulk magnet. The modulation with the wave vector , by virtue of magnetoelasticity,…
Valley current in graphene through electron-phonon interaction
Ankang Liu, Alexander M. Finkel'stein
We discuss valley current, which is carried by quasiparticles in graphene. We show that the valley current arises owing to a peculiar term in the electron-phonon collision integral…
