The low-temperature magnetic excitations of the two-dimensional spin- 52 square-lattice Heisenberg antiferromagnetRb2MnF4 have been probed using pulsed inelastic neutron scattering. In addition to dominant sharppeaks identified with one-magnon excitations, a relatively weak continuum scattering is also observed at higherenergies. This is attributed to neutron scattering by pairs of magnons and the observed intensities are consistentwith predictions of spin wave theory.

In this project, the team designed and built Paranormal, a free and open source normal map editor on OSX for 2D graphic artists. Apportable’s goal is to fill a missing link in the open source toolchain of applications that developers use to create iOS games. Normal maps make it possible for artists to incorporate 3D effects such as lighting and refraction, into 2D mobile games.
