Congratulations to Marvin Warner on his Successful PHD Defense
On July 2, 2025, Marvin Warner, a true homegrown talent of the University of Bremen, successfully defended his PhD thesis entitled: “Enabling Ultra-High Vacuum for Quantum Optical Instruments in Space.”
Marvin Warner is a true homegrown talent of the University of Bremen. He already wrote his master's thesis on the topic: “Development of an Alkali Atom Source for Experiments with Ultracold Atoms in Microgravity” at ZARM. Since July 2017, he has been supporting the "Quantum Technologies" research group at ZARM and on July 2, 2025 he successfully defended his PhD thesis entitled: “Enabling Ultra-High Vacuum for Quantum Optical Instruments in Space.”
His research focuses on fundamental investigations of ultra-high vacuum systems for experiments with cold atoms. This is a key technology for the development of novel quantum sensors that enable ultra-precise measurement capabilities for new technologies, for example, to better monitor our environment and support navigation.
Marvin applied the developments from his doctoral work in the BECCAL project (Bose-Einstein Condensate and Cold Atom Laboratory), where he leads engineering activities together with the head oft he research group Jens Grosse. Noteworthy contributions include the development and characterization of a degassing rate measurement system for assemblies, the implementation and characterization of alkali metal sources, and procedures for simulating vacuum pressure distribution using MOFLOW+.
Jens Grosse is pleased that Marvin is part of the team:
“Marvin takes innovative approaches and independently works on the complex challenges we face every day in BECCAL. And the fact that he also contributes to the cohesion of the team through his activities outside the office is something that everyone greatly appreciates.”
Marvin Warner:
“From the very first second, I was fascinated by ZARM and especially by all the quantum technology activities in microgravity. To this day, I love talking about ZARM, the drop tower, space exploration, and all kinds of experiments. It's simply a very special place, with so many dedicated and smart people.”
Congratulations on successfully completing your doctorate!
