International School

Tutzing, April 1-4, 2025

The Collaborative Research Center Open System Control of Atomic and Photonic Matter (OSCAR) explores the physics of open quantum many-body systems across different experimental platforms. Apart from basic research in this field the integrated young reseacher training program i-OSCAR guarantees education of the highest quality standards for the involved doctoral students and early postdocs. As a particular educational measure our SFB organized an International School on Open Quantum Many-Body Systems, which took place in the Evangelische Akademie in Tutzing (Germany), in the period April 1-4, 2025. The lectures focused on three research areas, which are of central importance of OSCAR and were discussed from both the experimental and the theoretical point of view:

1) Rydberg Systems:

a) Shannon Whitlock (Straßbourg, France):

Blueprint for a neutral atom quantum computer: Abstract and Slides

b) Hans-Peter Büchler (Stuttgart, Germany):

Rydberg atoms in optical tweezers for quantum simulation: Abstract and Slides

2) Quantum Fluids of Light:

a) Maciej Pieczarka (Wroclaw, Poland):

Optical potentials for exciton-polariton condensates: Abstract and Slides

Thermalization and Bose-Einstein condensation of photons in semiconductor laser cavities: Abstract and Slides

b) Jean-Jacques Greffet (Paris, France):

Controlling spontaneous emission with cavities, nanoantennas and collective effects: Abstract and Slides

A statistical physics approach to model photon Bose-Einstein condensation in semiconductor cavities and lasing: Abstract and Slides

3) Quantum Droplets:

a) Sebastian Will (New York, USA):

Creating a Bose-Einstein condensate of dipolar molecules and Exploring novel quantum phases with strongly dipolar molecules: Abstract and Slides1 and Slides2

b) Antun Balaz (Belgrade, Serbia):

Theory of quantum droplets in ultracold atomic and molecular gases: Abstract and Slides

Additionally, we had an Evening Lecture on the hot topic of Quantum Turbulence:

Vanderlei Bagnato (São Carlos, Brazil):

Turbulent trapped superfluid: Characterization of developed turbulence and relaxation to new equilibrium: Abstract and Slides
