The mechanisms discussed are local inertial forces (Coriolis and centrifugal), and current-current interaction with an external source. The primary application is to cosmology, but we also discuss the reduction to the non-relativistic nonlinear Schr¨odinger equation, which is widely used in describing superfluidity and vorticity in liquid helium and cold-trapped atomic gasesenResearch Subject Categories::NATURAL SCIENCES::Physicsrelativistic superfluidityquantized vorticitynonlinear Klein-Gordon equationArticle
