Findings

Multiparticle boson states arise from chaotic current dynamics.

Compact equations relate density operator, generating functional, and current correlator.

Bose-Einstein condensation is linked to external pulse effects.

Abstract

Multiparticle boson states, proposed recently for 'independently' emitted pions in heavy ion collisions, are reconsidered in standard second quantized formalism and shown to emerge from a simplistic chaotic current dynamics. Compact equations relate the density operator, the generating functional of multiparticle counts, and the correlator of the external current to each other. 'Bose-Einstein-condensation' is related to the external pulse. A quantum master equation is advocated for future Monte-Carlo simulations.
