Kutatás

My research activity focuses on many-body physics with applications to condensed matter and nanotechnology.  I am interested in emergent phenomena and the collective behavior arising from quantum mechanical and strong correlation effects. I have a strong background in quantum field theoretical methods and extensive technical expertise in the numerical simulation of low-dimensional and molecular systems. I am a passionate and versatile scientist. My research experience naturally spans topics from different fields of quantum physics, material science, and chemistry, which I can tackle with a broad range of analytical and numerical techniques.

 

Reseach Topics:

  • Diagrammatic and numerical methods for strongly correlated electrons
  • Many-body effects -- from the bulk to the nanoscale
  • Molecular electronics
  • Quantum dynamics of many-body systems
