Martin Fertl

Prof. Dr. Martin Fertl is a physicist at the Johannes Gutenberg University Mainz, leading research in the Quantum-, Atomic- and Neutron Physics (QUANTUM) group within the Institute of Physics. His work focuses on high-precision measurements of fundamental particles like neutrons, muons, and neutrinos to test the Standard Model of Particle Physics and Cosmology.

• Current projects include tSPECT (neutron lifetime via magnetic bottle technique) and contributions to the Muon g-2 experiment at Fermilab (measuring the muon's anomalous magnetic moment at 140 ppb precision).
• He also leads participation in the Project 8 collaboration, pioneering cyclotron radiation emission spectroscopy (CRES) with tritium and $^{83m}$Kr to determine neutrino mass.

Supported by the PRISMA+ Cluster of Excellence and the aMUSE project (European Commission grant 101006726), his research emphasizes magnetic field control, detector innovation, and computational methods for fundamental physics experiments. Recent publications highlight machine learning applications in CRES event reconstruction and precision magnetometry in cryogenic environments.
