Congratulations to Sofia… for her Postdoctoral Fellow at NASA Jet Propulsion Laboratory.
The 2017 Onassis Lectures in Physics on Quantum frontiers explored with cold atoms, molecules and photons was in the Honour of Serge Haroche. This year’s Nobel Prize Winner, Alain Aspect, was also one of the speakers.
Our proposal “Matter-Wave Interferometers” (MAWI) for an EU Doctoral Training Network has been ranked first in the Physics Panel in Europe! (the only one with a score of 99%).
The Cretan BEC group has hence one PhD position to fill. Please write to Wolf von Klitzing for details.
Congratulations to Pandora Examilioti for her viva, which she passed with excellence!
Mary Georgousi will start a master on Space Optics with us. Her project will be an ultra-compact, double compensated, highly stable saturation spectroscopy suitable for space projects.
Saurabh was the driving force behind this. He believed that this paper could go far and made sure that these great results get the attention it deserves. The effort paid of — thanks and congratulations to the whole team!

In this Letter, we demonstrate magnetogravitational matter-wave lensing as a novel tool in atom-optics in atomtronic waveguides. We collimate and focus matter waves originating from Bose-Einstein condensates and ultracold thermal atoms in ring-shaped time-averaged adiabatic potentials. We demonstrate “delta-kick cooling” of Bose-Einstein condensates, reducing their expansion energies by a factor of 46 down to 800 pK. The atomtronic waveguide ring has a diameter of less than one millimeter, compared to other state- of-the-art experiments requiring zero gravity or free-flight distances of ten meters and more. This level of control with extremely reduced spatial requirements is an important step toward atomtronic quantum sensors.
