On the microscopic formulation of landau theory of phase transitions
TLDR
In this article, the group-theoretical determination of the order parameters can be formulated in terms of the invariance properties of the Hamiltonian of the system, which avoids taking into consideration the phenomenological character of the free energy and its analytic expansion.About:

Phase Transitions in Cellular Automata.
TL;DR: In this paper, the authors introduce the notion of critical exponents, which is defined as a set of exponents that characterize the behavior of a phase transition in a macroscopic system with respect to specific values of intensive variables such as temperature or the magnetic field.

Quadrupole Phase Transitions in Magnetic Solids
H. H. Chen,Peter M. Levy +1 more
TL;DR: In this article, the phase transition of magnetic systems with large biquadratic interactions in the molecular field approximation was studied, and it was shown that the quadrupole and dipole phase transitions occur at different temperatures whenever the BIC interactions are greater than the bilinear terms for effective spin interactions.
