Spin waves in doped graphene: a time-dependent spin-density-functional approach to collective excitations in paramagnetic two-dimensional Dirac fermion gases
Matthew J. Anderson, Florent Perez, Carsten A. Ullrich
In spin-polarized itinerant electron systems, collective spin-wave modes arise from dynamical exchange and correlation (xc) effects. We here consider spin waves in doped paramagnet…
Chirality and intrinsic dissipation of spin modes in two-dimensional electron liquids
Irene D'Amico, Florent Perez, Carsten A. Ullrich
We review recent theoretical and experimental developments concerning collective spin excitations in two-dimensional electron liquid (2DEL) systems, with particular emphasis on the…
Spin precession and spin waves in a chiral electron gas: beyond Larmor's theorem
Shahrzad Karimi, Florent Baboux, Florent Perez +3
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: f…
Coulomb-driven organization and enhancement of spin-orbit fields in collective spin excitations
Florent Baboux, Florent Perez, Carsten A. Ullrich +3
Spin-orbit (SO) fields in a spin-polarized electron gas are studied by angle-resolved inelastic light scattering on a CdMnTe quantum well. We demonstrate a striking organization an…
Giant Collective Spin-Orbit Field in a Quantum Well: Fine Structure of Spin Plasmons
Florent Baboux, Florent Perez, Carsten A. Ullrich +3
We employ inelastic light scattering with magnetic fields to study intersubband spin plasmons in a quantum well. We demonstrate the existence of a giant collective spin-orbit (SO)…
Spin waves in magnetic quantum wells with Coulomb interaction and exchange coupling
Florent Perez, Joel Cibert, Masha Vladimirova +1
We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous wor…
Dynamical Corrections to Spin Wave Excitations in Quantum Wells due to Coulomb Interactions and Magnetic Ions
Cynthia Aku-Leh, Florent Perez, Bernard Jusserand +2
We have measured dispersions of spin-flip waves and spin-flip single-particle excitations of a spin polarized two-dimensional electron gas in a CdMnTe quantum well using resonant R…
Spin polarized two-dimensional electron gas embedded in semimagnetic quantum well : ground state, spin responses, spin excitations, Raman spectrum
F. Perez
We present theoretical aspects of spin polarized two dimensional electron gas (SP2DEG) which can be achieved in doped semimagnetic quantum wells. This original model system has bee…
Measuring the spin polarization and Zeeman energy of a spin-polarized electron gas: Comparison between Raman scattering and photoluminescence
Cynthia Aku-Leh, Florent Perez, Bernard Jusserand +5
We compare resonant electronic Raman scattering and photoluminescence measurements for the characterization of a spin-polarized two-dimensional electron gas embedded in $\text{Cd}_…
