Majorana particles are real solutions of the Dirac equation, representing their own antiparticles. In the condensed matter context, Majorana refers to electronic modes in nanostructures described by peculiar ‘pulled-apart’ wavefunctions and by hypothesized non-Abelian exchange.

This last property makes them interesting for quantum computing. I will present our efforts to generate and verify Majorana modes in semiconductor nanowires coupled to superconductors. In particular, how can we tell Majorana signatures apart from similar Andreev states that do not have non-Abelian properties?

While we may not have a verified Majorana observation now, I will talk about ways to get there: through careful experiments, improved nanowires and device fabrication and with eyes open for alternative explanations.

Speaker: Prof. Sergei Frolov is an experimentalist in the field of condensed matter physics. At TU Delft, used to investigate spin physics in nanowire quantum dots and superconductivity induced in semiconductors. Now at the University of Pittsburgh, he is responsible for a new low temperature quantum transport laboratory.
