We discuss novel aspects of the interaction of axions-like particles (ALP) with superfluids, superconductors in particular, and determine an induced Berry phase that is topologically singular and contributes to the generation of string-like structures. The latter are similar to vortices in superfluids. We suggest that measuring the currents generated by the Berry phase of ALP axions would enable the study of low mass regions of the ALP spectrum otherwise unobservable.

Abstract
We discuss novel aspects of the interaction of axions-like particles (ALP) with superfluids, superconductors in particular, and determine an induced Berry phase that is topologically singular and contributes to the generation of string-like structures. The latter are similar to vortices in superfluids. We suggest that measuring the currents generated by the Berry phase of ALP axions would enable the study of low mass regions of the ALP spectrum otherwise unobservable.File in questo prodotto:
