Gravity-induced birefringence in spherically symmetric spacetimes
Sebastian Murk, Daniel R. Terno, Rama Vadapalli
Geometric optics effectively describes the propagation of electromagnetic waves when the wavelength is much smaller than the characteristic length scale of the medium, making wave…
Light rings and causality for nonsingular ultracompact objects sourced by nonlinear electrodynamics
Sebastian Murk, Ioannis Soranidis
We study observational signatures of nonsingular ultracompact objects regularized by nonlinear electrodynamics. The phenomenon of birefringence causes photons of different polariza…
Categorical Quantum Volume Operator
Alexander Hahn, Sebastian Murk, Sukhbinder Singh +1
We present a generalization of the quantum volume operator quantifying the volume in curved three-dimensional discrete geometries. In its standard form, the quantum volume operator…
