Physics Colloquium

A New Era in Quantum Optics: From Topological Photonics to Correlated Materials
Mohammad Hafezi, UMD,

Quantum optics investigates the interactions between light and matter
at their most fundamental level. In recent years, we have witnessed
remarkable advances in controlling individual photons and other
excitations, such as spin, charge, excitons, and phonons, in
solid-state systems. While this progress has primarily been driven by
quantum information science (QIS), its implications extend far beyond
QIS. In this talk, I will present two key examples. First, I will
review the field of topological photonics, highlighting how optical
nonlinearity can give rise to unique bosonic phenomena—without
electronic counterparts—such as topological frequency combs and
topological sources of quantum light. Next, I will discuss how optical
control techniques can introduce a radically new approach for
preparing, detecting, and manipulating correlated electronic states.
This includes new ways of inducing and enhancing magnetism,
superconductivity, and topological phases in matter, as well as the
prospect of addressing some of the long-standing questions in the
field.
