Nanoscale superconductivity and quantum transport in 2D materials. Common factor is to model transport of charge, energy, and spin accounting for various types electron scattering processes and coupling to internal (quantum) degrees of freedom. The physics of 2D materials span over whole spectra of possible correlated systems, including unconventional superconductivity and magnetic ordering. Properties of these materials are externally tuneable by electrostatic doping and there is a plethora possible properties that can be explored and exploited for different opto-electrical applications.
Condensed matter theory with focus on quantum transport theory in strongly correlated electron systems. His research involves development of efficient numerical studies of charge and energy transport in spatially inhomogeneous systems based on non-equilibrium many body theory.
Focus of future research:
- photocurrent generation and charge carrier transport in photovoltaic devices based on 2D materials using the non-equilibrium Green’s function formalism.
- develop efficient numerical tools to model and explore carrier dynamics and transport in 2D heterotructures
- properties of nanoscale superconducting materials and devices
Highlights of previous research:
Adatoms on top of a graphene sheet can significantly modify the conductivity and plasmonic properties of graphene and may produce a level splitting in the plasmon mode. The effect is explored for sensing.
