Abundant production of scalars and axions from phase transition bubble expansion
Isabel Garcia Garcia, Gaurang Ramakant Kane, John March-Russell +1
We revisit aspects of particle production during cosmological first-order phase transitions, and show that the expansion of true-vacuum bubbles can be a copious source of particle…
Compact space catalysis of false vacuum decay and Schwinger effect
Saquib Hassan, John March-Russell
We study zero-temperature false vacuum decay in compact spatial dimensions and show that for volumes below a critical value a new bounce solution, different from Coleman's cele…
A prototype differential atom interferometer for fundamental physics
C. F. A. Baynham, R. Hobson, O. Buchmueller +89
Gravitational waves and ultralight dark matter are among the most compelling frontiers in fundamental physics, motivating proposals for Very Long-Baseline Atom Interferometers (VLB…
A more effective QCD string at colliders: Decay of excited strings and the worldsheet axion
Ethan Carragher, John March-Russell
The confining flux tube of d QCD is described by an effective string theory with d worldsheet action that extends the Nambu-Goto form by the addition of a massive pse…
Characterisation of silicon photomultipliers in a dilution refrigerator down to 9.4 mK towards a cryogenic cosmic-ray muon veto system
DMC Collaboration, A. Kemp, S. Autti +30
We report the characterisation of a FBK NUV-HD-cryo silicon photomultiplier (SiPM) sensor operated in a 9.4 0.2 mK environment inside a dilution refrigerator, towards the dev…
Probing the Dark Matter EFT with QUEST-DMC: Projected Sensitivities and Attenuation Ceilings
DMC Collaboration, N. Darvishi, S. Autti +27
This proceedings contribution summarises projected constraints from the QUEST-DMC concept, a surface-based direct-detection experiment using superfluid He operated below the mi…
