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.

18. July 2025 5:00 pm  Perspectives on modern climate change from 67 years of direct atmospheric measurements

Prof. Ralph Keeling, GEOSCIENCES RESEARCH DIV., Scripps Institution of Oceanography, UC San Diego,At the forefront of modern climate change research are time-series observations of atmospheric CO2 and related species, such as atmospheric O2. These records now span many decades, providing unequivocal evidence of the profound influence of humans on the planet - particularly through the burning of fossil fuels.more...

New Light on Quantum Physics

Julian Schmitt recently joined the Kirchhoff Institute for Physics – bringing fresh momentum to the field of quantum optics. With his new research group Optical Quantum Systems, he aims to explore how light and matter behave in the quantum world. Johanna Schwarz, administrative director of the faculty, spoke with him about his research and plans in Heidelberg.
