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.

Ruperto Carola Lecture Series 200 Years Gustav Kirchhoff

Free spirit. Pioneer. Visionary: Gustav Kirchhoff's scientific findings are still of great importance today for many current research topics. As the founder of spectral analysis in the 19th century, the outstanding physicist (1824 to 1887) not only paved the way for modern astrophysics, but also environmental physics, modern atomic and molecular physics, chemistry and quantum physics still use spectroscopy today. And without Kirchhoff's rules for electrical networks, chip development and the analysis of electrical circuits would be inconceivable.

The Ruperto Carola lecture series in the summer semester 2024 on the occasion of the 200th birthday of Gustav Kirchhoff, who researched and taught as a professor at Heidelberg University for more than 20 years, provides - in addition to a historical introduction to Kirchhoff's life and work - insights into areas of modern research on which Kirchhoff's work has had an influence to this day.

Physikalisches Kolloquium

13. December 2024 5:00 pm  Capturing Innovations and Underlying Physics in Sports

Prof. Chang Kee Jung, Department of Physics and Astronomy, Stony Brook University, New York, USA , Sports occupy an important part of our lives. It is often difficult to flip through the TV channels without encountering sports shows. Surprisingly, a large fraction of the intriguing and often spectacular sports actions and feats can be explained using relatively basic physics concepts. In this talk, I will present and discuss the physics behind some remarkably creative innovations in popular sports (baseball, soccer/football, volleyball, basketball, high Jump, gymnastics and swimming) using basic concepts in classical physics. more...

Probing the Superfluid and Solid Properties of a Dipolar Supersolid

Abstract: For a supersolid state to exist, it must spontaneously break two types of symmetry: phase (gauge) symmetry, which imparts superfluid-like properties, and translational invariance, which gives it solid-like characteristics. A key question is: how do the expected superfluid and solid properties modify each other in the presence of both?

In these talks, we will explore recent theoretical and experimental advances in understanding supersolids in dipolar quantum gases, focusing first on their superfluid properties through quantum vortex nucleation and the application of these results to develop a quantum simulator of a rotating neutron star, followed by their solid properties through shear wave propagation.
