Chiral Photonics & Symmetry Breaking
Symmetry-breaking light–matter interactions in low-dimensional quantum materials
Overview
We investigate symmetry-breaking light–matter interactions in low-dimensional quantum materials, with a particular focus on chiral and circularly polarized optical responses. By controlling polarization, crystal symmetry, and dimensionality, we reveal how broken symmetries give rise to unconventional photonic phenomena. Our approach combines polarization-resolved spectroscopy with device-level measurements to uncover chiral optical functionalities. These studies provide fundamental insight into symmetry-driven optoelectronic behavior and open pathways toward chiral photonic devices.
