John Doyle's research centers on trapping neutral
particles, study of fundamental collisional processes
in atoms and molecules, and lab and underground-observatory-based
searches for physics beyond the Standard Model. He
is also currently working to realize new techniques
to trap molecules and atoms and produce intense beams
of the same.
The Doyle group has pioneered a general technique for
cooling and loading atoms and molecules into traps.
First demonstrated with atomic europium and chromium
and molecular CaH, the technique uses cryogenic helium
buffer gas to cool atoms to below 1 Kelvin. The cold
atoms are then loaded into a magnetic trap and then
evaporatively cooled. This has led to the discovery
of several new findings on the physics of cold collisions
as well as doubling the number of species magnetically
trapped, including exotic atoms such as Dy. In addition,
by developing a new technique for producing heavy,
polar radical molecules in an intense beam, he has
launched with collaborators a new EDM search. Heavy,
highly polar molecules are ideally suited to the search
for a permanent electric dipole moment (EDM) in the
electron. The discovery of an EDM in these experiments
would indicate new physics beyond the standard model.
Work towards production of ultracold molecules aims
also to build hybrid quantum devices. Finally, work
is ongoing to use XUV scintillation in liquid neon
and argon to search for a key Dark Matter candidate,
the WIMP.
