Bell's theorem shows that no local hidden-variable model can explain the measurement statistics of a quantum system shared between two parties, thus ruling out a classical (local) understanding of nature. In this paper we demonstrate that by relaxing... Read More about Witnessing Bell violations through probabilistic negativity.

Perfect Chirality with Imperfect Polarization (2022)
Journal Article
Lang, B., McCutcheon, D. P., Harbord, E., Young, A. B., & Oulton, R. (2022). Perfect Chirality with Imperfect Polarization. Physical Review Letters, 128(7), Article 073602. https://doi.org/10.1103/physrevlett.128.073602

Unidirectional (chiral) emission of light from a circular dipole emitter into a waveguide is only possible at points of perfect circular polarization (C points), with elliptical polarizations yielding a lower directional contrast. However, there is n... Read More about Perfect Chirality with Imperfect Polarization.
