Overview

I am a theoretical physicist with a broad range of research interests spanning from exactly-solvable problems in quantum and statistical mechanics and anyon excitons in the fractional quantum Hall effect regime to THz applications of carbon-based nanostructures and modelling white light-emitting diodes. My most recent work is related to zero-energy states in graphene, excitons in narrow-gap carbon nanotubes and optical properties of two-dimensional materials with tilted Dirac cones.

Pleasa, contact me directly at m.e.portnoi(at)exeter.ac.uk  if you are interested in PhD study under my supervision. A choice of projects in the theory of low-dimensional condensed matter systems is available.

Further details of my research can be found here.
