    Talk (UK-APP one-day meeting)

    Axions are well-motivated dark matter candidates originally proposed to resolve the strong CP problem in quantum chromodynamics. In this talk, I present recent results from the Haloscope At Yale Sensitive To Axion Cold Dark Matter (HAYSTAC) experiment, which searches for axion dark matter using a tunable microwave cavity coupled to a quantum squeezed state receiver. HAYSTAC has scanned axion...

    Talk (UK-APP one-day meeting)

    False vacuum decay (FVD) is at the heart of many open questions in cosmology and fundamental physics including, for example, eternal inflation, baryon asymmetry, and Higgs stability. Semiclassical lattice simulations have recently been proposed as a way of describing the phenomenon in real time. These numerical methods will be complemented by upcoming tabletop experiments based on cold-atom...

    Talk (UK-APP one-day meeting)

    The Relic Axion Detector Exploratory Setup (RADES) collaboration works on the development of new techniques for axion searches. Axions are hypothetical pesudoscalar pseudoNambu-Goldstone bosons that appear as part of the solution to the the strong CP problem of QCD. At the same time they could also be the answer to one of the most puzzling questions on cosmology, the Dark Matter problem.

    Talk (UK-APP one-day meeting)

    We investigate how matter density distributions affect thin-wall bubble formation in the asymmetron mechanism, a scalar–tensor theory with a universal coupling to matter and explicit symmetry-breaking, and analyse the stability of its metastable state. We show that the screening mechanism of the asymmetron inside dense objects induces a surface tension associated with the boundary of the...
