UNCONVENTIONAL SCALING THEORY FOR DOMAIN GROWTH IN THE ALTERNATING BOND GLAUBER-ISING CHAIN

The domain growth after a quench is controlled by an exponent which generally has very broad universal properties. We investigate the alternating bond Ising chain with Glauber dynamics, and find that its growth exponent is universal, even though the dynamical critical exponent z is non-universal. We show that usual scaling theory can be reformulated to account for the above findings.
