Description
We present an analysis of the nonequilibrium dynamics of a broad family of excited states of the Schrodinger Poisson equations. An initial spherically symmetric, groundstate soliton is stretched or squeezed and is let to freely evolve, thereby forming the soliton halo system. We investigate the mechanism of virialisation, including the observed scalar field bursts[1] and their connection to the soliton breathing mode. The family of excitations studied samples particularly well the region of core-halo mass relations in which the soliton mass is much larger than the halo mass.
