TITLE:            New developments in topological phases of matter

ABSTRACT:
Quantum effects at a macroscopic scale underpin some of the fascinating phenomena in condensed matter physics ranging from superconductivity to topological phases of matter.  The interplay of quantum physics and topology underlies this year’s Nobel Prize for “strange forms of matter”. These “strange” phases manifest robust quantization of macroscopic observables independent of microscopic details and material imperfections. Recently, some of these phases have been realized in various platforms such as photonic systems and ultracold atomic gasses. The phase of the electromagnetic wave in photonic systems mimics the phase of the wavefunction granting a remarkable control over essential properties of topological phases, which in turn enables novel and robust photonic designs. In this talk, I will cover these recent developments and outline how one can look for “stranger” forms of matter and how they can be harnessed for future technology.
