High Q0 research The dynamics of flux trapping in superconducting niobium [PDF]

open access: yes, 2013
The quality factor Q0 that can be obtained in a superconducting cavity is known to depend on various factors like niobium material properties, treatment history and magnetic shielding. We believe that cooling conditions have an additional impact, as they

Granular Solid Hydrodynamics (GSH): a broad-ranged macroscopic theory of granular media

open access: yes, 2014
A unified continuum-mechanical theory has been until now lacking for granular media, some believe it could not exist. Derived employing the hydrodynamic approach, GSH is such a theory, though as yet a qualitative one.
