Multi-messenger astronomy, the coordinated observation of different classes of signals that originate from the same astrophysical event, provides a wealth of information about astrophysical processes. Many of the open questions of modern physics suggest the existence of exotic fields with light quanta (masses << 1 eV). Quantum sensor networks could be used to search for astrophysical signals that are predicted by theories beyond the standard model.

We show that networks of precision quantum sensors that, by design, are insensitive to conventional standard model physics signals can be a powerful tool for multi-messenger astronomy. These include global networks of atomic magnetometers and atomic clocks.

Considering the case in which high-energy astrophysical events produce intense bursts of exotic low-mass fields (ELFs), we propose a novel model for the potential detection of ELF signals. We find that such precision quantum sensor networks can function as ELF telescopes to detect signals from sources that generate ELF bursts of sufficient intensity.

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 Lewis Williamson to register your interest.

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