Enhancing image contrast using coherent states and photon number resolving detectors
, 2010 We experimentally map the transverse profile of diffraction-limited beams using photon-number-resolving detectors. We observe strong compression of diffracted beam profiles for high detected photon number.

Gaussian and Airy wave packets of massive particles with orbital angular momentum [PDF]
, 2015 While wave-packet solutions for relativistic wave equations are oftentimes thought to be approximate (paraxial), we demonstrate that there is a family of such solutions, which are exact, by employing a null-plane (light-cone) variables formalism.
