From atomic magnetometry to image memory

HI all,

The second Optics Group Optical Sciences Seminar will be given by Francesco Castellucci. The talk is titled "From atomic magnetometry to image memory", and will be given on 18th July at 15:00 in Kelvin Room 222.

Abstract:

The spherical orientation of a magnetic field can be seen through the interaction between light with Orbital Angular Momentum (OAM) and a cold atomic cloud. Applying two vector vortex beams to a cloud of atoms, the azimuth angle of the magnetic field is seen in the linear rotation of the transmitted pattern, and the inclination is reflected in a fracturing of the observed image. Using a similar setup it should be possible for any kind of complex beam to be stored in the magnetic dipoles of the atoms.

Unfortunately I cannot make it. However, Sara Restuccia will host the Seminar and provide snacks in the common room afterwards.
