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)…
Real-time electron dynamics with exact-exchange time-dependent density-functional theory
H. O. Wijewardane, C. A. Ullrich
The exact exchange potential in time-dependent density-functional theory is defined as an orbital functional through the time-dependent optimized effective potential (TDOEP) method…
Non-adiabatic electron dynamics in time-dependent density-functional theory
C. A. Ullrich, I. V. Tokatly
Time-dependent density-functional theory (TDDFT) treats dynamical exchange and correlation (xc) via a single-particle potential, Vxc(r,t), defined as a nonlocal functional of the d…
Intersubband spin-density excitations in quantum wells with Rashba spin splitting
C. A. Ullrich, M. E. Flatte
In inversion-asymmetric semiconductors, spin-orbit coupling induces a k-dependent spin splitting of valence and conduction bands, which is a well-known cause for spin decoherence i…
Time-dependent current density functional theory for the linear response of weakly disordered systems
C. A. Ullrich, G. Vignale
This paper develops a quantitatively accurate first-principles description for the frequency and the linewidth of collective electronic excitations in inhomogeneous weakly disorder…
Collective charge-density excitations of non-circular quantum dots in a magnetic field
C. A. Ullrich, G. Vignale
Recent photoabsorption measurements have revealed a rich fine structure in the collective charge-density excitation spectrum of few-electron quantum dots in the presence of magneti…
