The Speller Lab is located on the Homewood Campus of Johns Hopkins University in the Bloomberg Center for Physics and Astronomy. Our lab focuses on searches for rare events and new particles, particularly focusing on the search for neutrinoless double-beta decay and axion dark matter.
Searching for Neutrinoless Double-Beta Decay with CUORE
The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton-scale bolometer experiment located deep underground in Laboratori Nazionali del Gran Sasso in Gran Sasso, Italy. CUORE is optimized to look for lepton number symmetry violation via the neutrinoless double-beta decay of 130Te. An observation of this decay would yield new insight into the nature of the neutrino mass, and possibly new clues into the origin of the observed matter-antimatter asymmetry in the universe.
Looking for Axion Dark Matter with the HAYSTAC Experiment
The Haloscope At Yale Sensitive to Axion CDM (Cold Dark Matter) is a tunable microwave cavity experiment at Yale University. HAYSTAC searches for axion dark matter from the galactic halo by looking for the conversion of axions to photons in the presence of a strong magnetic field.
The CUPID Experiment
The project CUPID is an upgrade of the CUORE experiment, aiming at searching for neutrinoless double beta (0νββ) decay with Li2MoO4 scintillating crystals enriched in 100Mo.
The Axion Dark Matter Project
The Axion DM project leverages the convergence of expertise in axion physics, dark matter detection, material science and cosmology at Stockholm University.
