Welcome
Welcome to the topological matter theory research group at Columbia University. We investigate quantum phenomena of condensed matter systems and are fascinated with symmetry and topology. We explore how topology crucially influences fundamental characteristics of solid-state materials.
News
Welcome Nish!
Nishchhal Verma join us as a postdoc. Nish is interested in the interplay between topology and superconductivity in quantum materials, among many other things. We are delighted to have you join the team, Nish!
We are hiring!
Jointly with Prof. Andrew Millis the topological matter group is searching for a new postdoctoral scientist interested in topological and strongly correlated properties of moire heterostructures. Don't hesitate to contact me if you are interested or know of any interested candidates.
Applications are encouraged to arrive before September 30.
Topological Quantum Matter live on edX!
I am very pleased to announce that our Topological Quantum Matter online courseis finally live! A project with my colleagues and friends at Weizmann Institute.
Check the trailer here and enroll at https://www.edx.org/course/topological-states-of-matter for access to all the material.
Research Projects
Classification of topological matter
Topological phases appear in many forms and shapes. We strive for a exhaustive understanding of the topology of condensed matter systems, studying novel phases, novel invariants and boundary signatures.
Disordered topological matter
Dirt and impurities are unavoidable in real physical systems. They break translation symmetry and invalidate Bloch's theorem. But can we still find order in disorder? Are there topological invariants that subside these harsh conditions?
