DOI: 10.1002/andp.202500202
Abstract: Axions are considered a key component of dark matter, characterized by very weak couplings to fermions and Chern‐Simons couplings to gauge fields. We propose a novel detection mechanism based on symmetry‐breaking magnetoelectric materialswith a linear… read more here.

DOI: 10.1007/978-3-030-43761-9_12
Abstract: The QUAX proposal studies the interaction of dark matter axions with electrons. As the effect of axions can be described as an effective magnetic field, the signal is a magnetization oscillation of a sample. To… read more here.

DOI: 10.1007/jhep01(2025)077
Abstract: We discuss a QCD-scale composite axion model arising from dark QCD coupled to QCD. The presently proposed scenario not only solves the strong CP problem, but also is compatible with the preheating setup for the… read more here.

DOI: 10.1007/jhep01(2025)132
Abstract: If dark matter carries a baryon number of two, neutron-antineutron oscillations could require its presence to manifest themselves. If it is in addition very light, in the micro-eV range or up to a few orders… read more here.

Abstract: A bstractThe QCD axion’s coupling to photons is often assumed to lie in a narrow band as a function of the axion mass. We demonstrate that several simple mechanisms, in addition to the photophilic clockwork… read more here.

Abstract: A bstractWe discuss inflation models within supersymmetry and supergravity frameworks with a landscape of chiral superfields and one U(1) shift symmetry which is broken by non-perturbative symmetry breaking terms in the superpotential. We label the… read more here.

Abstract: We study the dynamics and interactions of the solitonic domain walls that occur in realistic axion electrodynamics models including the Chern-Simons interaction, aϵμνλσFμνFλσ, between an axion a(x) of mass ma, and a massless U(1) gauge… read more here.

Abstract: We show that axion dark matter in the range meV ≲ ma ≲ 100 meV can incoherently excite phonons in crystal targets with unpolarised nuclear spins. This can occur through its coupling to nuclear spins… read more here.
