The GiaSaaS mission to send a Greek satellite into space has just been selected. It will be lead by OHB-Hellas and encompasses a Pan-Greek consortium of companies and universities, including the Libre-Space-Foundation, the National Observatory of Athens, the The Microprocessors Laboratory and Digital Systems Lab of the NTUA, the Greek Center for Security Studies (KEMEA).
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.
Our latest PRL entitled “Atomtronic Matter-Wave Lensing”, which has just been published in Physical Review Letters, is featured as a synopsis in Physics.APS.org with the catchy title: “How to Focus a Bose-Einstein Condensate in a Waveguide”.

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!
Vangelis Tzardis is has been accepted a the PhD in Frederick University in Cyprus to work on the identification and prediction of brain tumors from MR images.
Congratulations from the BEC team!
Good news: Our new ESA project: Greek InfrAstructure for Satellite as a Service: GIASaaS (headed by OHB-Hellas) has been selected for evaluation!

We study the spectral signatures and coherence properties of radiofrequency dressed hyperfine Zeeman sub-levels of 87Rb. Experimentally, we engineer combinations of static and RF magnetic fields to modify the response of the atomic spin states to environmental magnetic field noise. We demonstrate analytically and experimentally the existence of ‘magic’ dressing conditions where decoherence due to electromagnetic field noise is strongly suppressed. Building upon this result, we propose a bi-chromatic dressing configuration that reduces the global sensitivity of the atomic ground states to low-frequency noise, and enables the simultaneous protection of multiple transitions between the two ground hyperfine manifolds of atomic alkali species. Our methods produce protected transitions between any pair of hyperfine sub-levels at arbitrary (low) DC-magnetic fields.
