Abstract: We study how to improve the precision of the quantum estimation of phase for an uniformly accelerated atom in fluctuating electromagnetic field by reflecting boundaries. We find that the precision decreases with increases of the… read more here.

Abstract: Abstract In this paper we derive analytical solutions for potential problems on different types of surfaces, such as cylinders, cones and spheres. These solutions complement the solution obtained for a sphere. Besides examining modes of… read more here.

Abstract: For surfaces without boundary, nonlocal notions of directional and mean curvatures have been recently given. Here, we develop alternative notions, special cases of which apply to surfaces with boundary. Our main tool is a new… read more here.
