Sonja Bernitt

Sonja Bernitt is a researcher at the Helmholtz Institute Jena, affiliated with Friedrich Schiller University Jena. Her work spans atomic physics, quantum field theory, and X-ray spectroscopy, focusing on high-intensity laser interactions with ionic targets and relativistic quantum dynamics.

Research interests include:

• Quantum logic spectroscopy of highly-charged heavy ions
• Soft X-ray spectroscopy and microscopy
• High purity X-ray polarimetry
• Development of quantum field theory models at extreme intensities

She contributes to experimental facilities like the POLARIS and JETI lasers, and collaborates with institutions such as GSI, DESY, and FAIR.
