TITLE:
The search for the quirky quantum particle struck gold: The emergence of
Majorana fermions in condensed matter physics and implications
SPEAKER:
Professor Sumanta Tewari,
TIME: Wednesday April 3, 2013 at 4:00 PM
PLACE: Room 101 Olin Physical Laboratory
ABSTRACT
Majorana fermion (MF), the elusive quantum particle proposed more than seven decades ago by E. Majorana to describe neutrinos, is finally beginning to be experimentally realized in condensed matter systems. Following our recent proposal to realize them in semiconductor-superconductor heterostructures, at least four experimental groups worldwide have claimed success in observing them in various experiments. In this talk I will introduce the physics of the MFs, why they are technologically important (topological quantum computation), our proposal for MFs in condensed matter systems, and the subsequent experimental realizations that have been reported and created enormous interest in topological quantum condensed matter physics.
