Kirchhoff Institute for Physics

The Kirchhoff Institute for Physics (KIP) is named after a prominent physicist of the 19th Century: Gustav Robert Kirchhoff, who worked in Heidelberg for 21 years. His well-known lectures on experimental and theoretical physics attracted many students. Kirchhoff's ground-breaking research was extraordinarily diverse, spanning electrical, magnetic, optical, elastic, hydrodynamic and thermal processes. His laws for electrical circuits are well-known. At the time he was in Heidelberg, in conjunction with Robert Wilhelm Bunsen, he discovered spectral analysis and its application to solar radiation. In this way, Kirchhoff laid the foundation for modern astrophysics, as well as formulating the laws of thermal radiation, which played a key role in the discovery of quantum physics. The KIP aims to continue in this tradition of diverse scientific research and education.

Breakthrough of the Year 2023

We are thrilled that our results on simulating quantum fields in curved and expanding spacetimes was chosen as a Top 10 Breakthrough of the Year 2023 by Physics World magazine! The project, developed together with the group of Stefan Flörchinger (Uni Jena), explored how a gas of ultra cold potassium atoms can be used to implement analogue spacetimes. By controling the local density and interaction between the atoms, we can implement spacetimes of arbitrary spatial curvature, as well as cosmological expansion. We use phonons (sound waves) in our cloud as an analogue to photons in a 'real' universe, and investigate fascinating phenomena like cosmological particle production.
