RESEARCH

I've studied superconductivity in systems without translational symmetry, in particular, superconducting junctions. I'm also interested in spin related phenomena in superconducting systems, such as proximity effect in ferromagnet/superconductor junctions. My recent main interests are spintronics and topological systems.

In this project, I will investigate Weyl superconducting phases in superconductors without inversion symmetry. I will also propose device applications of Weyl superconductors.
