The University of Amsterdam hosts the Strontium Quantum Gases group of Florian Schreck, who is also the AQuRA coordinator. The group uses strontium quantum gases to study quantum many-body physics and for precision measurement. Besides the AQuRA project, five other projects are also pursued:
Within AQuRA Amsterdam will deliver micro-optics based laser frequency distribution and control hardware, the control electronics and the physics package control software for the clock. This is based on our open source hardware and software platform. The micro-optics systems and the control solutions will be made commercially available through our spin off Firefly Quantum by 2025. Amsterdam will also contribute to the development of the AQuRA physics package in collaboration with the Syrte and Torun groups to build a precise portable passive optical lattice clock. We do have open PhD and postdoc positions. Strontium Quantum Gases group webpage: www.strontiumBEC.com |

Florian Schreck uses ultracold quantum gases to explore quantum physics. After his PhD 2002 at E.N.S. Paris with Christophe Salomon and a postdoc in Austin, TX with Mark Raizen, he joined the group of Rudolf Grimm at IQOQI, Innsbruck in 2004. He founded his own research group in 2008, soon afterwards creating the first quantum gas of strontium. Another important breakthrough was to reach quantum degeneracy using only laser cooling. In 2014 he moved his group to Amsterdam, where he extended his research using an ERC consolidator grant and an NWO Vici grant. He is the coordinator of the AQuRA consortium and was coordinator of the related iqclock and MoSaiQC consortia.

Shayne Bennetts (postdoc) has worked on developing steady state ultracold Strontium gases at the University of Amsterdam since 2014. His PhD project aimed a make the first continuous-wave atom laser. On Christmas morning of 2019 together with lab partner Chun-Chia Chen he made the first continuously existing BEC, a continuous-wave atom laser without outcoupling. In former lives he worked with ultracold rubidium at the Australian National University and on some of the early thulium and holmium fiber lasers, solid state lasers and the OZDIRCM project with the Australian DST group.

Sumit Sarkar (postdoc) is a passionate physicist with a strong background in experimental quantum optics. During his PhD, his research focused on pioneering work in the realm of atom lasers and quantum simulations using cold atoms. Subsequently, his expertise expanded into the field of metrology and precision measurements using quantum sensors. He worked as a postdoc at SYRTE, Paris in the team of Prof. Franck Pereira to develop state of art quantum gradiometer. His current research pursuits revolve around the innovation of novel cold atom quantum sensors, showcasing his commitment to advancing the frontiers of quantum technology.

Mehrdad Zarei (postdoc) started his journey in ultracold quantum gases in 2020 as a PhD from the MoSaiQC project at KL FAMO group with Michal Zawada in Nicolaus Copernicus University. He was involved in clock automation by developing an auto relocking system for ECDLs and automatic control of magnetic fields of compensation coils to make the clock more robust and easier to operate. He tested the developed system on a Rydberg laser for an optical tweezers machine project at Florian Schreck group and Toptica company. He was also involved in optimizing and operating a Strontium optical lattice clock to test the stability of his system. He has joined the Florian Schreck Group as a postdoc in the AQuRA project Since March 2024.

Rodrigo Escudero González (postdoc) is a researcher with a background in quantum gases and laser physics. He earned his PhD from the University of Amsterdam, where he focused on developing novel sources of steady-state ultracold strontium atoms and steady-state quantum gases. Currently, he is a Postdoctoral Research Fellow, working on frequency distribution networks using both ultra-stable lasers and the white rabbit time and frequency distribution protocol. In his free time, he enjoys spending time with his cat, Minoes (the miauster in chief), and working on personal programming projects, such as topbets.ai.

Amber Visser is a master’s student in Physics and Astronomy at the University of Amsterdam. She previously studied at Utrecht University, where she worked on several projects the largest of which was designing and building a topological chain using a scanning tunneling microscope. She first worked with laser systems during an internship in the second year of her bachelor’s and has not been able to get away since (despite trying).
