Oriana Diessel

About me

I am a Ph.D. student in theoretical physics in the group of Dr. Richard Schmidt.
My research focuses on few-and many-body phenomena in ultracold gases.

Research interests:

  • Ultracold Fermi gases with quantum impurities
  • Spectroscopy protocols in ultracold atoms
  • Polaron physics
  • Nonequilibrium field theoretical methods
  • Variational methods

I joined the Theory Division of the Max Planck Institute of Quantum Optics in October 2019.
Currently, I am working on Fermi polaron physics. In particular, I am developing a theoretical description of Raman and Ramsey spectroscopy protocols in ultracold atoms with quantum impurities.
Furthermore, I am interested in collective phenomena arising in quantum light-matter systems.

Before joining the MPQ, I completed my undergraduate studies at the University of Cologne.  My MSc thesis focussed on many-body instabilities in Moiré flatband systems using the functional renormalization Group (FRG).
