Berry Curvature. For years, physicists have worked towards the ability to directly measure Berry curvature. Often discussed as a "holy grail," this observation has seemed impossible to make until now.

Abstract. In this paper, we consider n-dimensional oriented complete hypersurfaces with constant scalar curvature of a Euclidean space ℝn+1. We characterize the hypersurface Sk(c) × ℝn−k in a ...
