We mourn the death of

Prof. Dr. Ernst Brun

Professor Emeritus of Experimental Physics
born on March 31, 1927, deceased on November 19, 2022 at the age of 95 years

Ernst Brun was Professor for Experimental Physics at the Physics Institute of the University of Zurich from 1957 until his retirement in 1994. He studied physics at the University of Zurich and received his doctorate under the supervision of Professor H.H. Staub in 1954 with a thesis on the magnetic moments of ytrium, potassium and silver. After a research visit in the USA, he was appointed Associate Professor for Experimental Physics at the University of Zurich in 1957.

His diverse scientific activities focused on the study of complex non-linear systems (chaos and order) by NMR and laser methods, which led to the discovery of the NMR laser (Raser) in his research group.

In addition to his in-depth special lectures, Ernst Brun taught medical students for many years as a great and dedicated teacher in lectures that remained in the lasting memory of many. In doing so, he succeeded in conveying to his audience the fascination of researching fundamental physical questions, and in introducing physics as a basic subject to the future scientists.
Ernst Brun served as Dean of the Faculty of Mathematics and Natural Sciences from 1970 to 1972 and as Director of the Physics Institute of the University of Zurich from 1972 to 1992.

In Ernst Brun, the University of Zurich, his colleagues and former students have lost a person and mentor to whom they owe a great tribute.


Research at the Physik-Institut

Research at the Physik-Institut covers both experimental and theoretical physics. Experimental activities include the physics of biological systems, nanometer structures and surface physics, fundamental properties of materials and high-temperature superconductivity as well as accelerator and non-accelerator based elementary-particle and astroparticle physics. Theoretical research concentrates on precision calculations of processes in quantum chromodynamics and on fundamental aspects of high-energy physics.

Schrödinger Gleichung


Erwin Schrödinger invented his famous equation during the time he was a professor for theoretical physics at our University and received the Nobel prize for his achievements in 1933. Solutions to Schrödinger's equation describe most quantum mechanical features of atomic and molecular systems.
