Zoltán Harman

Zoltán Harman is a Leading Scientist at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg, Germany, and is affiliated with Heidelberg University. He conducts cutting-edge research in atomic physics, quantum electrodynamics, and precision measurements, particularly using highly charged ions and Penning trap techniques. He holds a habilitation in physics from Heidelberg University and regularly lectures there on advanced topics such as quantum electrodynamics and theoretical physics.

Research Interests:

• Quantum Electrodynamics (QED) in strong fields
• Precision spectroscopy of highly charged ions
• g-factor measurements and tests of fundamental physics
• Development of atomic clocks using highly charged ions
• Determination of fundamental constants (e.g., electron mass, fine-structure constant)
• Searches for new physics beyond the Standard Model, including fifth forces
• Neutrino mass determination via Penning trap measurements

His recent publications (2024–2025) focus on high-precision g-factor measurements in ions like tin and beryllium, two-loop QED calculations, King plot analyses for new boson searches, and neutrino mass studies. These works appear in top journals such as Nature, Physical Review Letters, and Science, reflecting his leadership in precision atomic physics.

Scientific Awards and Grants:

• Postdoctoral scholarship from the Max Planck Society (2005–2007)
• EMMI Visiting Professor Scholarship (2012, 2013)
• Erasmus student scholarship (1999–2000)
• Primary investigator of the ISOQUANT Collaborative Research Centre (SFB1225)

Teaching and Advising: Harman has been a regular lecturer at Heidelberg University since 2008, teaching courses in quantum electrodynamics, theoretical physics, and experimental physics. He co-organizes advanced lecture series and supervises student research projects, including poster sessions and talks. He is also a lecturer in the International Max Planck Research School on Quantum Dynamics.

Research Group and Collaborations: Harman is a key member of the quantum dynamics group at MPIK, led by Prof. Christoph H. Keitel. His work involves close collaboration with experimental teams at MPIK, GSI, and Heidelberg University, combining theoretical and experimental efforts in precision physics. He is actively involved in major projects such as PENTATRAP and ALPHATRAP, which aim to push the limits of atomic and nuclear measurements.
