Unconventional discontinuous transitions in a two-dimensional system with spin and valley degrees of freedom

ZM Raines, LI Glazman, AV Chubukov - Physical Review B, 2024 - APS
We analyze the transition into the most favorable ordered state for a system of 2D fermions
with spin and valley degrees of freedom. We show that for a range of rotationally invariant …

Collective spin modes in fermi liquids with spin–orbit coupling

DL Maslov, A Kumar, S Maiti - Journal of Experimental and Theoretical …, 2022 - Springer
A combination of spin–orbit coupling and electron–electron interaction gives rise to a new
type of collective spin modes, which correspond to oscillations of magnetization even in the …

Phonon-induced collective modes in spin-orbit coupled polar metals

A Kumar, P Chandra, PA Volkov - Physical Review B, 2023 - APS
We study the interplay between collective electronic and lattice modes in polar metals in an
applied magnetic field aligned with the polar axis. Static spin-orbit coupling leads to the …

Collective spin oscillations in a magnetized graphene sheet

M Agarwal, OA Starykh, DA Pesin, EG Mishchenko - Physical Review B, 2024 - APS
We investigate collective spin excitations of graphene electrons with short-ranged
interactions and subject to the external Zeeman magnetic field. We find that in addition to the …

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 …

Impact of the impurity symmetry on orbital momentum relaxation and orbital Hall effect studied by the quantum Boltzmann equation

VV Kabanov, AV Shumilin - arXiv preprint arXiv:2410.04934, 2024 - arxiv.org
We develop a quantum Boltzman equation approach that incorporates microscopic impurity
models into the theory of orbital transport, revealing, how impurity properties, including their …
