Symmetry & Chirality


molecular properties  |  electromagnetics  |  spectroscopy

We have broad interests in the interaction of optical, electric, and magnetic fields with matter. We develop new experimental methods and instrumentation for the detection and identification of molecules as well as the separation of enantiomers. A particular focus at present is electromagnetic forces, light-matter interactions, and symmetry breaking & any new effects it gives rise to.

Our work in the news


We have specific interests in:

Chiral molecules & optical activity

Chiral molecules are routinely detected by observing the rotation of a plane polarized light beam that traverses an “optically active” liquid. We recently showed that the same can be achieved at a single interface in refraction and reflection. This effect has allowed us to build the first microfluidic chiral refractometer.
