I am a theoretical condensed
matter physicist with a broad interest in quantum many-body physics relevant to
experiments. At present, I am predominantly interested in applying topological
principles to create protected solid-state and cold-atomic systems for quantum
information processing. Such topological phenomena might provide the basis for
quantum information processing.
Advances in experimental physics
have pushed the design of materials and devices towards the regime of quantum
many-body physics. At the same time conceptual advances at the boundary of
theoretical condensed matter, quantum information and high-energy physics such
as topological quantum field theories, entanglement entropy, holography and
many-body localization all point to a new era of understanding new quantum
mechanical many-body phenomena. I am primarily interested in searching for
manifestations of these beautiful ideas in phenomena in the real world. One
such phenomenon, which is at the heart of topological quantum field theory, is
topological degeneracy of quantum states. Such degeneracy is a macroscopic
quantum phenomenon where two many-body quantum states of the system are at
exactly the same energy in a way that is immune to external perturbations.
Potential candidates for topological superconductors that could support
Majorana fermions and are being studied in on-going experiments provide
examples of phases with similarly protected degeneracy. This creates the
potential of storing and manipulating quantum information in macroscopic states
of quantum materials, and ultimately, of leading to platforms for topological
quantum computation. I am also interested in the search for quantum many-body
phenomena in other systems where topological principles such as Weyl systems
and spin-orbit coupled Bose gases as well as Josephson junction arrays.
