Searching for New Fundamental Physics with Polyatomic Molecules
Nick Hutzler (Caltech, California Institute of Technology, USA)

The fact that the universe is made entirely out of matter, and contains no free anti-matter, has no physical explanation.
The unknown process that created matter in the universe must violate a number of fundamental symmetries, including those that forbid the
existence of certain electromagnetic moments of fundamental particles whose signatures are amplified by the large internal fields in polar
molecules. We discuss spectroscopic and theoretical investigations into polyatomic molecules that uniquely combine multiple desirable
features for precision measurement, such as high polarizability through symmetry-lowering mechanical motions, novel electronic and
bonding structures, laser cooling, and exotic nuclei.
