The order parameter-entropy relation in some universal classes: experimental evidence

J. M. Martin-Olalla, F. J. Romero, S. Ramos +3

The asymptotic behaviour near phase transitions can be suitably characterized by the scaling of $\Delta s/Q^2$ with $\epsilon =1-T/T_c$, where $\Delta s$ is the excess entropy and $Q$ is the order par…
