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…
Scale-dependent theory of the disordered electron liquid
A. M. Finkel'stein, G. Schwiete
We review the scaling theory of disordered itinerant electrons with e-e interactions. We first show how to adjust the microscopic Fermi-liquid theory to the presence of disorder. T…
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,…
The role of electron-electron collisions for magnetotransport at intermediate temperatures
Woo-Ram Lee, Alexander Finkel'stein, G. Schwiete
We discuss galvanomagnetic and thermomagnetic effects in disordered electronic systems focusing on intermediate temperatures, for which electron-electron scattering and electron-im…
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…
