Abstract Strong spin-orbit interactions make hole quantum dots central to the quest for electrical spin qubit manipulation enabling fast, low-power, scalable quantum computation. Yet it is important to establish to what extent spin-orbit coupling exp

Phonon-polaritons (PhPs) arise from the strong coupling of photons to optical phonons. They offer light confinement and harnessing below the diffraction limit for applications including sensing, imaging, superlensing, and photonics-based communicatio

Fluid dynamics is one of the cornerstones of modern physics and has recently found applications in the transport of electrons in solids. In most solids, electron transport is dominated by extrinsic factors, such as sample geometry and scattering from

We demonstrate that the Berry curvature monopole of nonmagnetic two-dimensional spin-$3/2$ holes leads to a novel Hall effect linear in an applied in-plane magnetic field ${B}_{\ensuremath{\parallel}}$. Remarkably, all scalar and spin-dependent disor
