I am interested in topological signatures in molecular magnetic quantum materials for plausible applications in quantum computation. In the recent past I worked on cuprates and iron-based superconductors. These systems are strongly correlated and host myriads of fascinating phenomena both in homogeneous state and in presence of impurities and defects. In particular, multiband iron-based superconductors are in vicinity of magnetic instability that can show competing interplay with superconductivity, inducing topological characters in the system. Topologically non-trivial superconductors have been particularly interesting in recent times because of their capability to host zero-energy modes which in turn can have application in robust fault tolerant quantum computation.
