Dark matter axions and other highly degenerate bosonic fluids are commonly described by classical field equations. In a recent paper \cite{BECprop} we calculated the duration of classicality of homogeneous condensates with attractive contact interactions and of self-gravitating homogeneous condensates in critical expansion.

Massive photon-like particles are predicted in many extensions of the Standard Model with a hidden sector where dark matter is secluded. They are vector bosons mediating the interaction between dark matter particles and can be produced in scattering of ordinary particles through a faint mixing to the photon. [...]

In this contribution, we highlight a problem in estimation of the mass of axion dark matter in the scenario where the Peccei-Quinn symmetry is broken after inflation. In order to obtain a definite prediction for its mass, it is necessary to evaluate its relic abundance precisely by taking account of the production from cosmic strings and domain walls. [...]

Among solutions of the strong CP problem, the "invisible'' axion in the narrow axion window is argued to be the remaining possibility among natural solutions on the smallness of $\bar{\theta}$. Related to the gravity spoil of global symmetries, some prospective "invisible'' axions from theory point of view are discussed. [...]

Phenomenology of Majorons

Majorons are the Goldstone bosons associated to lepton number and thus closely connected to Majorana neutrino masses. Couplings to charged fermions arise at one-loop level, including lepton-flavor-violating ones that lead to decays $\ell\to \ell' J$, whereas a coupling to photons is generated at two loops. [...]

Here we present the specifications of the newly developed beta-spectrometer based on thick full absorption Si(Li) detector. The spectrometer can be used for precision measurements of various beta-spectra, namely for the beta-spectrum shape study of $^{144}$Pr, which is considered to be the most promising anti-neutrino source for sterile neutrino searches..

The sub-micron range in the field of short distance interactions has yet to be opened to experimental investigation, and may well hold the key to understanding al least part of the dark matter puzzle. The aKWISP (advanced-KWISP) project introduces the novel Double Membrane Interaction Monitor (DMIM), a combined source-sensing device where interaction distances can be as short as 100 nm or even 10 nm, much below the $\approx 1-10$ $\mu$m distance which is the lower limit encountered by current experimental efforts.

We report the results of studies showing that temperature dependent photoluminescence is the likely source of unexpected large background rates in afterglow searches for dark sector phenomena, commonly called ``chameleons''. Using this information, we examine the possibility of a room temperature chameleon afterglow search that automatically eliminates this background. [...]
