Abstract

I present a brief overview of some novel detection strategies for ultra-low-mass bosonic dark matter that forms a coherently oscillating classical field. Possible effects of such dark-matter fields include time-varying fundamental constants and time-varying spin-precession effects. These effects can be sought with a diverse variety of precision, low-energy (and often) table-top experiments, including: spectroscopy (clock) and optical cavity measurements, laser interferometers, fifth-force (torsion pendula) experiments, magnetometry techniques, and big bang nucleosynthesis. Existing and new experimental and observational data have allowed us and other groups to improve on previous observational bounds on possible non-gravitational interactions of dark matter with ordinary matter by many orders of magnitude.

Brief Biography

I am currently a Kavli Fellow working on various topics in theoretical physics at the Kavli Institute for the Physics and Mathematics of the Universe in Japan. Previously, I was a Humboldt Research Fellow at the Helmholtz Institute Mainz in Germany. I completed my PhD in astroparticle and atomic physics under the supervision of Professor Victor Flambaum at the University of New South Wales in Australia. For my PhD research, I was awarded the Bragg Gold Medal by the Australian Institute of Physics for the best PhD thesis by a student from an Australian University.
