Gauge-Field-Mediated Symmetry Breaking of Matters Under Electromagnetic Fields and Its Impact on Spin Dynamics
Uiseok Jeong, Esmaeil Taghizadeh Sisakht, Angel Rubio +3
When a condensed-matter system is subjected to external electromagnetic fields, the gauge-invariant formulation of physical operators must explicitly incorporate the gauge-field co…
Current-Driven Symmetry Breaking and Spin-Orbit Polarization in Chiral Wires
Uiseok Jeong, Daniel Hill, Esmaeil Taghizadeh Sisakht +4
The spin dynamics of electrons in chiral molecular systems remain a topic of intense interest, particularly regarding whether geometric chirality inherently induces spin polarizati…
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 gaps and spin-flip energies in density-functional theory
K. Capelle, G. Vignale, C. A. Ullrich
Energy gaps are crucial aspects of the electronic structure of finite and extended systems. Whereas much is known about how to define and calculate charge gaps in density-functiona…
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…
