TeachingLecturer in the spotlightUvA News: Lecturer in the spotlight: Florian Schreck Introduction to quantum mechanics, part 3This lecture is aligned with Griffiths' 2nd edition chapters 5 to 7 and taught in the 2nd year of the bachelor during 14 hours. Full lecture as powerpoint presention: Quantum mechanics lecture FS.pptx (36MB). Full lecture as pdf: Quantum mechanics lecture FS.pdf (17MB).
Bose-Einstein condensationIn this lecture, I explain how a Bose-Einstein condensate (BEC) of ultracold atoms is created in the lab. During the first three lectures basic atom-light interaction properties are derived. Lectures 4 to 5 explain laser cooling and trapping. Lecture 6 introduces evaporative cooling and Bose-Einstein condensation. In lecture 7 the experimental characterization of some BEC properties are explained. Finally I give an overview of some of our current research projects. This lecture was taught in autumn 2014 to 2020 in the physics master's programme of the University of Amsterdam. It was accompanied by a lecture on the theory of BEC by Gora Shlyapnikov. Full lecture as powerpoint presention: BEC_Lecture_UvA_FS_2021.pptx (111MB).

Quantum simulationIn this lecture, I explain how ultracold quantum gases can be used to study quantum physics in the spirit of quantum simulation. It was taught in spring 2015 in the physics master's programme of the University of Amsterdam. It was accompanied by a lecture on the theory of Fermi quantum gases by Gora Shlyapnikov.
