Expected Sensitivity to Galactic/Solar Axions and Bosonic Super-WIMPs based on the Axio-electric Effect in Liquid Xenon Dark Matter Detectors

open access: yes, 2013
We present systematic case studies to investigate the sensitivity of axion searches by liquid xenon detectors, using the axio-electric effect (analogue of the photoelectric effect) on xenon atoms.

Notes from the 3rd Axion Strategy Meeting [PDF]

open access: yes, 2010
In this note we briefly summarize the main future targets and strategies for axion and general low energy particle physics identified in the "3rd axion strategy meeting" held during the AXIONS 2010 workshop.

Colonization and extinction lags drive non‐linear responses to warming in mountain plant communities across the Northern Hemisphere

open access: yesEcography, EarlyView.
Global warming is changing plant communities due to the arrival of new species from warmer regions and declining abundance of cold‐adapted species. However, experimentally testing predictions about trajectories and rates of community change is challenging because we normally lack an expectation for future community composition, and most warming ...

Classification of three-family flavoured DFSZ axion models that have no domain wall problem

open access: yesJournal of High Energy Physics
We provide an exhaustive classification of three-family DFSZ axion models that have no cosmological domain wall problem. This result is obtained by making the Peccei-Quinn symmetry flavour dependent in certain specific ways, thus reinforcing a possible ...

Stellar Evolution Bounds on the ALP-Photon Coupling: new Results and Perspectives

open access: yes, 2014
Stellar evolution considerations are of fundamental importance in our understanding of the axion/ALP-photon coupling, g_{a\gamma}. Helium burning stars are the best laboratories to study this coupling. Here, we will review the bounds from massive and low

New solar axion search in CAST with $^4$He filling [PDF]

open access: yes, 2015
The CERN Axion Solar Telescope (CAST) searches for $a\to\gamma$ conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward the Sun. Two parallel magnet bores can be filled with helium of adjustable pressure to match

Combined heat and drought affect the abundance, composition and diversity of subalpine surface‐active soil arthropod communities

open access: yesEcological Entomology, EarlyView.
We applied factorial soil warming and moisture reduction treatments directly in the field in the Australian subalpine to assess changes to surface‐active soil arthropod abundance, diversity and community composition. After identifying nearly 50,000 specimens to order, we found a stronger effect of sampling month than treatment.

Extra-dimensional axion expectations

open access: yesJournal of High Energy Physics
Axions arising as modes of higher-dimensional gauge fields are known to offer a compelling solution to the axion quality problem and to naturally arise in string theory.

Photon enhancement in a homogeneous axion dark matter background

open access: yes, 2019
We study the propagation of photons in a homogeneous axion dark matter background. When the axion decay into two photons is stimulated, the photon field exhibits a parametric instability in a small bandwidth centered on one half of the axion mass.

Cave depth and subterranean connectivity are drivers of intraspecific trait variability in two subterranean congeneric beetles

open access: yesEcological Entomology, EarlyView.
The abundance of cave beetles increases with depth, with Duvalius hartigi exhibiting maximum densities at greater depths in volcanic systems. Troglomorphic traits become more pronounced with increasing depth exclusively in the alpine species Duvalius carantii.
