On the Sensitivity of Spin-Precession Axion Experiments

Autor: Dror, Jeff A., Gori, Stefania, Leedom, Jacob M., Nicholas Rodd

Publikováno v: INSPIRE-HEP

A leading direction in the hunt for axion dark matter is to search for its influence on nuclear spins. The detection scheme involves polarizing a sample of nuclei within a strong static magnetic field and then looking for a spin precession induced by

Heterodyne Broadband Detection of Axion Dark Matter

Physical Review

We propose a new broadband search strategy for ultralight axion dark matter that interacts with electromagnetism. An oscillating axion field induces transitions between two quasi-degenerate resonant modes of a superconducting cavity. In two broadband

If the symmetry breaking responsible for axion dark matter production occurs during the radiation-dominated epoch in the early Universe, then this produces large amplitude perturbations that collapse into dense objects known as axion miniclusters. Th

Classical Nonrelativistic Effective Field Theory and the Role of Gravitational Interactions

Autor: Eby, Joshua, Mukaida, Kyohei, Takimoto, Masahiro, Wijewardhana, L. C. R., Yamada, Masaki

Coherent oscillation of axions or axion-like particles may give rise to long-lived clumps, called axion stars, because of the attractive gravitational force or its self-interaction. Such a kind of configuration has been extensively studied in the con

Refined Study of Isocurvature Fluctuations in the Curvaton Scenario

JCAP, 2017, 12 (12), pp.042. 〈10.1088/1475-7516/2017/12/042〉

We revisit the generation of dark matter isocurvature perturbations in the curvaton model in greater detail, both analytically and numerically. As concrete examples, we investigate the cases of thermally decoupled dark matter and axionic dark matter.
