Search for dark matter axions with CAST-CAPP
/ Adair, C.M. (British Columbia U.) ; Altenmüller, K. (Zaragoza U.) ; Anastassopoulos, V. (Patras U.) ; Cuendis, S. Arguedas (CERN) ; Baier, J. (Freiburg U.) ; Barth, K. (CERN) ; Belov, A. (Moscow, INR) ; Bozicevic, D. (Rijeka U.) ; Bräuninger, H. (Garching, Max Planck Inst., MPE) ; Cantatore, G. (INFN, Trieste ; Trieste U.) et al.
The CAST-CAPP axion haloscope, operating at CERN inside the CAST dipole magnet, has searched for axions in the 19.74 $\mu$eV to 22.47 $\mu$eV mass range. The detection concept follows the Sikivie haloscope principle, where Dark Matter axions convert into photons within a resonator immersed in a magnetic field. [...]

Search for streaming dark matter axions or other exotica
/ Gardikiotis, A (Patras U.) ; Anastassopoulos, V (Patras U.) ; Bertolucci, S (INFN, Bologna) ; Cantatore, G (U. Trieste (main) ; INFN, Trieste) ; Cetin, S (Istanbul Bilgi U.) ; Fischer, H (Freiburg U.) ; Funk, W (CERN) ; Hoffmann, D H H (XJTLU, Suzhou ; Moscow Phys. Eng. Inst.) ; Hofmann, S (Unlisted, DE) ; Karuza, M (Rijeka U. ; INFN, Trieste) et al.
We suggest a new approach to search for galactic axions or other similar exotica. Streaming dark matter (DM) could have a better discovery potential because of flux enhancement, due to gravitational lensing when the Sun and/or a planet are aligned with a DM stream [1]. [...]

aKWISP: investigating short-distance interactions at sub-micron scales
/ Cantatore, G. (INFN, Trieste ; Trieste U.) ; Anastassopoulos, V. (Patras U.) ; Cetin, S. (Istanbul Bilgi U.) ; Fischer, H. (Freiburg U.) ; Funk, W. (CERN) ; Gardikiotis, A.

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 1-10 micron distance which is the lower limit encountered by current experimental efforts.

New CAST Limit on the Axion-Photon Interaction
/ CAST Collaboration
During 2003--2015, the CERN Axion Solar Telescope (CAST) has searched for $a\to\gamma$ conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward the Sun. In its final phase of solar axion searches (2013--2015), CAST has returned to evacuated magnet pipes, which is optimal for small axion masses. [...]

Search for chameleons with CAST
/ CAST Collaboration
In this work we present a search for (solar) chameleons with the CERN Axion Solar Telescope (CAST). This novel experimental technique, in the field of dark energy research, exploits both the chameleon coupling to matter ($\beta_{\rm m}$) and to photons ($\beta_{\gamma}$) via the Primakoff effect.

The 11-years solar cycle as the manifestation of the dark Universe
/ Zioutas, K. (CERN) ; Tsagri, M. ; Semertzidis, Y.K. (Brookhaven) ; Papaevangelou, T. (IRFU, Saclay) ; Hoffmann, D.H.H. (Darmstadt, Tech. Hochsch.) ; Anastassopoulos, V. (Patras U.)
The solar luminosity in the visible changes at the 10-3 level, following an 11 years period. In X-rays, which should not be there, the amplitude varies 100000 times stronger, making their mysterious origin since the discovery in 1938 even more puzzling, and inspiring. [...]
