    AKWISP: Investigating short-distance interactions at sub-micron scales
    (Verlag Deutsches Elektronen-Synchrotron, 2017) Cantatore, G.; Anastassopoulos, V.; Cetin, S.; Fischer, H.; Funk, W.; Gardikiotis, A.; Hoffmann, D.H.H.
    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 ?m distance which is the lower limit encountered by current experimental efforts. aKWISP builds on the technology and the results obtained with the KWISP opto-mechanical force sensor now searching at CAST for the direct coupling to matter of solar chameleons. It will reach the ultimate quantum-limited sensitivity by exploiting an array of technologies, including operation at milli-Kelvin temperatures. Recent suggestions point at short-distance interactions studies as intriguing possibilities for the detection of axions and of new physical phenomena. © Proceedings of the 13th Patras Workshop on Axions, WIMPs and WISPs, PATRAS 2017.

    Search for streaming dark matter axions or other exotica
    (Verlag Deutsches Elektronen-Synchrotron, 2017) Gardikiotis, A.; Anastassopoulos, V.; Bertolucci, S.; Cantatore, G.; Cetin, S.; Fischer, H.; Funk, W.
    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]. Of interest are also axion miniclusters, in particular, if the solar system has trapped one during its formation. Wide-band axion antennae fit this concept, but also the proposed fast narrow band scanning. A network of detectors can provide full time coverage and a large axion mass acceptance. Other DM searches may profit from this proposal. © Proceedings of the 13th Patras Workshop on Axions, WIMPs and WISPs, PATRAS 2017. All rights reserved.
