An improved conjecture is proposed to give more precise predictions of the multicritical points than the conventional one, inspired by a different point of view coming from the renormalization group and succeeds in deriving very consistent answers with many numerical data.
CORRIGENDUM: Ground-state entropy and algebraic order at low temperatures
A rescaling argument is applied to systems with a highly degenerate ground state. It is suggested that these systems can exhibit a distinctive low-temperature phase in which correlations decay…
Renormalisation-group calculations of finite systems: order parameter and specific heat for epitaxial ordering
Renormalisation theory can be used to calculate the statistical properties of systems with arbitrary finite size. This method is demonstrated with the order parameter is and specific heat for…

Superfluidity and phase separation in helium films
A vectorial generalization of the Blume-Emery-Griffiths model is proposed to describe superfluidity in films of /sup 3/He-/sup 4/He mixtures, and is solved by an approximate renormalization scheme…

It is shown that frustration lowers in temperature the onset of both long- and short-range order in spin-glass phases, but is more effective on the former, while chaos increases with increasing frustration.
