Floquet topological superconductivity in two-dimensional magnet-superconductor hybrid systems.
ORAL
Abstract
Magnet-superconductor hybrid (MSH) systems have proven valuable candidate systems for the creation
of topological superconductivity and the ensuing Majorana zero modes. However, the manipulation of
this topological superconductivity, and in particular, the ability to externally tune MSH system
between topological and trivial phases, has remained a significant obstacle on the road to realizing
topological quantum computing. In this talk, I will demonstrate how the topological phases of MSH
systems can be manipulated by using periodically driven changes in their magnetic structure. In
particular, I will discuss how the interplay between the time and spatial dependence of the magnetic
structure can be employed to quantum engineer topological superconducting phases.
