Research Areas 
 Theoretical Condensed Matter Physics (strongly correlated electrons, quantum field theory, integrable systems, heavy fermions, superconductivity, nonequilibrium transport, mesoscopic systems, ultracold atomic gases, disordered elastic systems). 

Main interests 
 Prof. Bolech works in the area of theoretical condensed matter and his interests span several aspects of statistical and solid state physics. A large portion of his recent research involves complex quantum impurity models and their connections with correlated lattice systems and mesoscopic systems at the nanometer scale. Quantum impurities are one of the current paradigms of strongly correlated systems. In turn, dealing with strong interactions is one of the main theoretical challenges of presentday frontier problems not only in condensedmatter physics but also in atomic, nuclear and particle physics. Within condensedmatter physics, strong correlations are to be found in numerous systems such as heavy fermions, hightemperature superconductors, organic conductors, or quantum wires and dots; to name just a few. Bolech's work combines different computational and fieldtheoretic nonperturbative approaches to problems like the optical response of Mott insulators, the interplay of mixed valence and multichannel Kondo physics in heavy fermions and quantum dots, and tunneling transport in unconventional superconductors.
