Conserved quantities and integrability for massless spinning particles in general relativity

Lars Andersson, Finnian Gray, Marius A. Oancea

In general relativity, the dynamics of spinning particles is governed by the Mathisson-Papapetrou-Dixon equations, which are most commonly applied to massive bodies, but the framew…

A mathematical description of the spin Hall effect of light in inhomogeneous media

Sam C. Collingbourne, Marius A. Oancea, Jan Sbierski

We study Gaussian wave packet solutions for Maxwell's equations in an isotropic, inhomogeneous medium and derive a system of ordinary differential equations that captures the leadi…

Quantum geometric tensors from sub-bundle geometry

Marius A. Oancea, Thomas B. Mieling, Giandomenico Palumbo

The geometric properties of quantum states are crucial for understanding many physical phenomena in quantum mechanics, condensed matter physics, and optics. The central object desc…

Pseudodifferential Weyl calculus on vector bundles

Lars Andersson, Benjamin Moser, Marius A. Oancea +2

We develop a geometric framework for Weyl quantization on pseudo-Riemannian manifolds, in which pseudodifferential operators act on sections of vector bundles equipped with pseudo-…

Gravitational wave memory and its effects on particles and fields

Abraham I. Harte, Thomas B. Mieling, Marius A. Oancea +1

Gravitational wave memory is said to arise when a gravitational wave burst produces changes in a physical system that persist even after that wave has passed. This paper analyzes g…
