Dr Michał Tomza

Since December 2017 I am a research assistant professor at the Faculty of Physics at the University of Warsaw where I have established a new research group working on the theory of quantum molecular systems:

Laboratory of Quantum Molecular Systems


(this webpage is NOT longer updated since 2016) 

I work on the intersection of theoretical atomic, molecular, and optical physics and quantum chemistry.

I am interested in engineering controllable quantum molecular systems for both fundamental research (from precision measurements to quantum simulations and computations) and upcoming quantum technologies.

Research interests:

  • Formation, properties, interactions, dynamics and control of ultracold molecules in external fields
  • Ultracold quantum gases of atoms and molecules / Quantum control
  • Quantum dynamics and simulations with ultracold polar molecules in an optical lattice
  • Ab initio electronic structure calculations
