Discrete Chiral Ballistic Polariton Laser

open access: yesLaser &Photonics Reviews, EarlyView.
Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.

Some nonlinear problems for the superposition of fractional operators with Neumann boundary conditions

open access: yesMathematische Nachrichten, EarlyView.
Abstract We discuss the existence theory of a nonlinear problem of nonlocal type subject to Neumann boundary conditions. Differently from the existing literature, the elliptic operator under consideration is obtained as a superposition of operators of mixed order. The setting that we introduce is very general and comprises, for instance, the sum of two

Fundamental solutions to the p-Laplace equation in a class of Grushin vector fields

open access: yesElectronic Journal of Differential Equations, 2011
We find the fundamental solution to the p-Laplace equation in a class of Grushin-type spaces. The singularity occurs at the sub-Riemannian points, which naturally corresponds to finding the fundamental solution of a generalized Grushin operator in ...

Substantia Nigra Iron Deposition in Lewy Body Disease: A Magnetic Resonance Imaging and Neuropathology Study

open access: yesMovement Disorders, EarlyView.
Abstract Objective To compare iron deposition in the substantia nigra (SN) as measured with quantitative susceptibility mapping (QSM) on antemortem magnetic resonance imaging (MRI) between individuals with and without Lewy‐related pathology at autopsy. Methods We performed a retrospective cohort study including 54 participants who underwent autopsy and
