Abstract

The authors study experimentally the spin dynamics of a spin-1 Bose-Einstein condensate under two different magnetic field regimes and discuss the competing effect of quantum fluctuations and a coherent seed. The experimental results are compared to theoretical predictions from classical, semiclassical, and quantum models.
