Laboratory demonstration of low order wavefront control using light reflected off the vortex coronagraph

Posted by klaurent Caltech

Kavli Affiliate: Dimitri Mawet| Summary:The Astro2020 Decadal Survey identified exoplanet imaging as a high priority for the Habitable Worlds Observatory (HWO), which must image and characterize exo-Earths at contrasts of $1times10^-10$. The vector vortex coronagraph (VVC) is a leading architecture for this task owing to its small inner working angle and high throughput. Using light […]

Symmetry, Sound, and the Quest for Chiral Superconductors

Posted by klaurent Cornell

Kavli Affiliate: Brad Ramshaw | Summary:The confirmation of a bulk, topological superconductor is a central goal of modern quantum materials research. Despite decades of searching, no confirmed examples yet exist. A primary difficulty is that most experimental signatures of topological superconductivity are ambiguous and indirect. I review efforts to narrow the search for a chiral […]
