Abstract

The universal scaling of macroscopic observables tells us about the loss of information on initial conditions and microscopic system properties. By studying the time evolution of an isolated spinor Bose gas after a sudden quench into a magnetically ordered phase, it is numerically shown that universal scaling evolution at a nonthermal fixed point is possible in a purely one-dimensional geometry.
