Collective modes in two-and three-dimensional electron systems with Rashba spin-orbit coupling
In addition to charge plasmons, a 2D electron system with Rashba-type spin-orbit coupling
(SOC) also supports three collective modes in the spin sector: the chiral-spin modes. We …

Electron spin resonance in a two-dimensional Fermi liquid with spin-orbit coupling
Electron spin resonance (ESR) is usually viewed as a single-particle phenomenon protected
from the effect of many-body correlations. We show that this is not the case in a two …

Spin precession and spin waves in a chiral electron gas: Beyond Larmor's theorem
Larmor's theorem holds for magnetic systems that are invariant under spin rotation. In the
presence of spin-orbit coupling this invariance is lost and Larmor's theorem is broken: for …

Spin waves in doped graphene: A time-dependent spin density functional approach to collective excitations in paramagnetic two-dimensional Dirac fermion gases
MJ Anderson, F Perez, CA Ullrich - Physical Review B, 2021 - APS
In spin-polarized itinerant electron systems, collective spin-wave modes arise from
dynamical exchange and correlation (xc) effects. We consider here spin waves in doped …
