Probing imperfect axions with nuclear clocks
Salvatore Bottaro, Andrea Caputo, Gilad Perez +2
We show that Th nuclear clocks can probe departures from the Peccei-Quinn (PQ) solution to the strong CP problem. Explicit PQ breaking or additional CP-violating interactio…
Influence of tides and self-gravity on Ultra-Light Dark Matter Bounds from Dwarf Galaxies
Andrea Caputo, Luca Teodori
Dwarf spheroidal galaxies provide some of the most sensitive astrophysical probes of ultra-light dark matter (ULDM), but the inferred constraints can be affected by two important s…
On the sensitivity of nuclear clocks to new physics
Andrea Caputo, Doron Gazit, Hans-Werner Hammer +4
The recent demonstration of laser excitation of the eV isomeric state of Thorium-229 is a significant step towards a nuclear clock. The low excitation energy likely res…
Neutrino emission in cold neutron stars: Bremsstrahlung and modified urca rates reexamined
Salvatore Bottaro, Andrea Caputo, Damiano Fiorillo
Neutrino emission in cold neutron stars is dominated by the modified urca (murca) process and nucleon-nucleon bremsstrahlung. The standard emission rates were provided by Friman an…
