# 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.

### Atomic Quantum Simulation of Abelian and non-Abelian Gauge Theories

* Prof. Uwe-Jens Wiese,
Institute for Theoretical Physics, Albert Einstein Center for Fundamental Physics, Fachbereich Physik, University of Bern*
Gauge theories, which realize symmetries locally in space and time, play an
important role in many areas of physics. In elementary particle physics, an
Abelian U(1) gauge symmetry governs the electromagnetic interaction between
electrons mediated by photons, while a non-Abelian SU(3) gauge symmetry
controls
the strong interaction between quarks mediated by gluons.
