Description

 

The IPPP hosts a workshop dedicated to emerging experimental approaches to searching for light dark matter, leveraging the step-change in quantum sensing technologies over the past decade.

 

Stringent constraints from direct detection experiments targeting weakly interacting massive particles (WIMPs) and challenges with small-scale structures in the universe have led to the exploration of alternative dark matter candidates beyond traditional WIMPs. Among the most promising is ultralight dark matter, whose detection through various tabletop experiments is increasingly important in the current era of precision science. These experiments involve expertise in particle, atomic, and condensed matter physics. The interaction between ultralight particles and standard model particles may give rise to macroscopic forces. Moreover, several equivalence principle tests provide complementary avenues for detecting these particles. This workshop will unite both theorists and experimentalists to delve into these topics, creating a platform to discuss cutting-edge trends and advancements in dark matter detection technologies.

        Ultralight dark matter haloes in galaxies

        An intriguing possibility for the nature of dark matter (DM) is to assume that DM consists of ultralight bosonic particles, which are present in various extensions of the Standard Model. These bosons may lead to unique quantum features on ∼ kpc scales, where they form solitons and possibly, vortex structures of a Bose-Einstein condensate. This leads to various astrophysical applications, which I will present in my talk: rotation curves, velocity dispersion, dynamical friction of baryonic matter, the DM vorticity and gravitational wave signatures in collisions of ULDM haloes.

        Testing Antimatter Couplings with (Matter-)Spectroscopy

        Spectroscopic observables in atoms and highly charged ions are sensitive to new scalar-mediated potentials. A scalar with Lorentz-violating couplings allows for a split into "matter" and "antimatter" couplings, at least in the non-relativistic limit. Naively, this requires spectroscopy of both matter and antimatter to disentangle them. In this talk, I will show that relativistic corrections lift this degeneracy already in ordinary hydrogen, giving indirect access to antimatter couplings from matter spectroscopy alone. In highly charged ions, enhanced relativistic effects amplify the sensitivity, compensating for reduced experimental precision and larger theoretical uncertainties. Astrophysical constraints, shown for comparison, provide strong bounds even on antimatter couplings, despite stars being predominantly composed of matter.
