Jittery Quantum Boomerang Effect
Pedro Dornelas, Gerson J. Ferreira
We study the dynamics of a spin-polarized wave packet in a disordered Rashba two-dimensional electron gas and identify a jittery quantum boomerang effect in which longitudinal and…
Physical Pictures for Quasisymmetry in Crystals
Bryan D. Assunção, Emmanuel V. C. Lopes, Tome M. Schmidt +1
Quasisymmetry (QS) provides a novel route to understand and control near-degeneracies, Berry curvature, optical selection rules, and symmetry-protected phenomena in quantum materia…
An Unusual Dresselhaus Spin-Orbit Contribution of Even Order in Momentum
Hao Yang, Wei Wang, Gerson J. Ferreira +3
The spin-orbit (SO) coupling is conventionally known to manifest as \emph{odd} functions of momentum. Here, through both model calculations and symmetry analysis along with the met…
Phase transitions and scale invariance in topological Anderson insulators
Bryan D. Assunção, Gerson J. Ferreira, Caio H. Lewenkopf
We investigate disordered-driven transitions between trivial and topological insulator (TI) phases in two-dimensional (2D) systems. Our study primarily focuses on the BHZ model wit…
Electrical control of spin relaxation anisotropy during drift transport in a two-dimensional electron gas
F. G. G. Hernandez, G. J. Ferreira, M. Luengo-Kovac +4
Spin relaxation was studied in a two-dimensional electron gas confined in a wide GaAs quantum well. Recently, the control of the spin relaxation anisotropy by diffusive motion was…
Orbital pseudospin-momentum locking in two-dimensional chiral borophene
Felipe Crasto de Lima, Gerson J. Ferreira, Roberto H. Miwa
Recently, orbital-textures have been found in Rashba and topological insulator (TI) surface states as a result of the spin-orbit coupling (SOC). Here, we predict a orbita…
