Pasquale Marra, PhD

I am a theoretical condensed matter physicist at the University of Tokyo.

I am interested in topological states of matter, superconductivity, and quantum computation. My recent work is focussed on Majorana bound states in topological superconductors, and on the emergence of topological phases induced by spatially modulated fields, in quantum nanostructures as well as in cold atoms trapped by coherent laser beams (optical lattices).
