Ultra-low-mass bosonic particles produced non-thermally in the early Universe may subsequently form an oscillating classical field that can comprise the observed cold dark matter.  The very high number density of such dark-matter particles can give rise to characteristic wave-like signatures that are distinct from the traditional particle-like signatures considered in searches for WIMP dark matter.  In particular, ultra-low-mass scalar dark matter may induce apparent variations of the fundamental “constants” of Nature.  I discuss the basic principles of and recent results in searches for ultra-low-mass scalar dark matter using precision low-energy experiments, including atomic spectroscopy, optical cavities and interferometry.

About Physics Seminars

The weekly Physics Seminar series focuses on a broad range of physics research within SMP, along with frequent presentations from visiting researchers. Seminars are usually scheduled for 1.00pm on Tuesdays.

The talks are typically more specialised than a colloquium but are often attended by staff and PhD students across a broad range of areas. Speakers are thus encouraged to include introductory material in the talks.

All SMP researchers and HDR students are encouraged to speak. Please email Glen Harris to register your interest.

The seminars are open so there is no need to register your attendance.
