Spontaneous Breaking of Spatial and Spin Symmetry in Spinor Condensates
Spontaneous Breaking of Spatial and Spin Symmetry in Spinor Condensates
Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric amplifier of spin modes, resulting in a twofold spontaneous breaking of spatial and spin symmetry in the amplified clouds. Our experiments permit a precise analysis of the …
