Research Description

David Patterson investigates time-reversal–violating forces in molecules to explore one of the deepest mysteries in physics: why the Universe contains more matter than antimatter. His research focuses on detecting subtle asymmetries in chiral molecules — mirror-image forms that may respond differently to the weak nuclear force. By combining ion trapping, microwave three-wave mixing, and high-precision spectroscopy, Patterson’s team aims to observe these effects for the first time, offering new insights into molecular structure and nuclear interactions at the intersection of chemistry and fundamental physics.

Research Impact

Professor Patterson’s research targets a subtle but profound prediction in molecular physics: that chiral molecules exhibit tiny structural differences due to parity violation by the weak nuclear force. Detecting this effect would confirm a preferred handedness in nature and offer new insight into the origins of life’s homochirality. His team’s technique — capable of measuring the chirality of a single molecule — also promises transformative applications in analytical chemistry, enabling ultra-sensitive detection and characterization of molecular structure.
