About Me
I am a Postdoctoral Researcher at Saarland University specializing in theoretical condensed matter physics. My doctoral research focused on Floquet engineering, topological superconductivity, dynamical quantum phase transitions, altermagnets, and non-Hermitian systems. Currently, my work centers on cavity QED materials and the application of two-dimensional coherent spectroscopy to probe magnetic systems.
