We understand theoretical condensed matter physics with emphasis on topological materials, strongly correlated electrons in low-dimensional systems. We develop many-body algorithms and perform large-scale numerical simulations. More specifically, we study the electronic structure and topological properties of material systems with density functional theory in a combination with many-body methods like dynamical mean-field theory (DMFT) and extensions like cluster DMFT, dynamical cluster approximation, dual-fermion approach, non-local expansion and parquet equations, etc. We are interested in the exotic phases and topologically protected surface states emerging from electronic correlations and nontrivial band topology, and we try to explain experimental observations with our calculations.

  Research Interest  
I am particularly interested in the correlated two-dimensional surface systems, transition metal oxides and related compounds with narrow d-bands, topological insulators, Dirac semimetals etc. The goal of my research is to hunt for new materials exhibiting exotic phases emerging from electronic correlations and nontrivial band topology by using advanced numerical methods. The numerical tools at hand include continuous-time quantum Monte Carlo (CT-INT and CT-HYB), dynamical mean-field theory (DMFT), dynamical cluster approach (DCA), cluster-DMFT (CDMFT), dual-fermion approach (DF), non-local expansion scheme (NLE) and parquet formalism. We have long-term experience of collaborating with experimental groups working on angle-resolved photoemission spectroscopy (ARPES) and Scanning Tunneling Spectroscopy (STM).
