Prof. Dr. Peter Fierlinger



Academic Career and Research Areas

Professor Fierlinger (b. 1978) conducts experiments designed to explore the material/antimaterial asymmetry of the universe. He primarily focuses on precision experiments with captured ultra cold neutrons, especially the measurement of the electric dipole moment of the neutron, physics with spin-polarized noble gases. A related focus are the development of ultra-low magnetic fields and magnetic shielding. Another focus is trying to determine the mass of the neutrino by means of neutrino-free double beta decay.

Professor Fierlinger completed his studies in physics in Vienna (2002). These studies included several periods of research at the Laue-Langevin Institute in Grenoble. After receiving a doctorate in Zurich (2005) he went to Stanford University (California). He was subsequently appointed to a position at TUM (2008). Professor Fierlinger leads the “Origin and Structure of the Universe” research group at the excellence cluster and is founder of Fierlinger Magnetics.
