„Topological Phases of Materials and Their Applications”

Abstract: In 2016, Nobel prize was awarded for discovery of topological phenomena in matter accounting for non-trivial phases and phase transitions. At the foundation we have the Kosterlitz-Thouless phase transitions and the Haldane model of spin chains with non-trivial edges. The non-trivial phenomena in these cases were explained using the mathematical concepts of Topology. The former and latter have led to the development of topological states of matter; redefining our understanding of condensed matter. Ever since, topological phases such as, topological insulators, semi-metals, superconductors, Kondo insulators etc. have been at the forefront of quantum materials unravelling unconventional physics. These materials find applications in numerous field such as, spintronics, nano-electronics, quantum computations, catalysis etc. Topological insulators host multi-functional properties making them even more promising. These materials are characterized by, insulation in N dimensions and conduction across N-1 dimensions. Such phenomena have been predicted theoretically and observed experimentally in bulk as well as low dimensional materials. Such non-trivial phase of matter can be observed either intrinsically or by employing various techniques such as, application of strain/stress, electric fields, functionalization, dimensional-engineering etc. We present, non-trivial topological quantum phases of matter in bulk and low dimensional materials and discuss future prospects in terms of applications.

Short-CV:
