Electronic cooling of a TiW alloy normal-metal island using Nb-based superconducting tunnel junctions
Joel Hätinen, Renan Pires Loreto, Arvind Kumar +2
TiW thin films remain non-superconducting down to millikelvin temperatures and are compatible with large-scale CMOS manufacturing, making them attractive for cryogenic and quantum…
Dipole Radiation and Kinetic Mixing from Dark Photon Solitons
Enrico D. Schiappacasse, Moira Venegas
Wave-like dark matter composed of spin-1 particles, known as dark photons, is theorized to form clumps called "vector solitons". These solitons are compact astrophysical objects th…
Setting up stasis with gravitational interactions
Andrew J. Long, Barmak Shams Es Haghi, Moira Venegas
An epoch known as cosmological stasis may have taken place in the early Universe. During matter-radiation stasis, a population of non-relativistic particles with different masses g…
Free streaming of warm wave dark matter in modified expansion histories
Andrew J. Long, Moira Venegas
In models of warm dark matter, there is an appreciable population of high momentum particles in the early universe, which free stream out of primordial over/under densities, thereb…
