Research interests

I am a PostDoc working in condensed matter theory and many-body quantum mechanics. My research interest focuses on models of strongly correlated electron-, spin- and electron-phonon systems; their quantum phase transitions and exotic phases, as well as the development of new computational tools and methods.
