Theory of Dynamic Critical Phenomena
TL;DR: The renormalization group theory has been applied to a variety of dynamic critical phenomena, such as the phase separation of a symmetric binary fluid as mentioned in this paper, and it has been shown that it can explain available experimental data at the critical point of pure fluids, and binary mixtures, and at many magnetic phase transitions.

Spin glasses: Experimental facts, theoretical concepts, and open questions
Kurt Binder,A. P. Young +1 more
TL;DR: In this article, the most characteristic properties of spin glass systems are described, and related phenomena in other glassy systems (dielectric and orientational glasses) are mentioned, and a review summarizes recent developments in the theory of spin glasses, as well as pertinent experimental data.

Critical phenomena and renormalization-group theory
Andrea Pelissetto,Ettore Vicari +1 more
TL;DR: In this paper, the critical behavior of spin systems at equilibrium is studied in three and two dimensions, and the results in three-dimensional space are presented in particular for the six-loop perturbative series for the β -functions.

Co-operative Jahn-Teller effects
G A Gehring,K A Gehring +1 more
TL;DR: The co-operative Jahn-Teller effect is a phase transition which is driven by the interaction between localized orbital electronic states and the crystal lattice as mentioned in this paper, and the possible origins, symmetries and properties of the electron-lattice interactions and how they lead to possible hamiltonians for the coupled system are discussed.

The study of structural phase transitions by means of ultrasonic experiments
TL;DR: In this paper, the effects of various processes occurring at a structural phase transformation on the quantities measured in an ultrasonic experiment are discussed and various theoretical approaches are discussed as well as experimental results.

Static Phenomena Near Critical Points: Theory and Experiment
Leo P. Kadanoff,Wolfgang Götze,David Hamblen,Robert Hecht,E. A. S. Lewis,V. V. Palciauskas,Martin Rayl,Jack Swift,D. E. Aspnes,Joseph W. Kane +9 more
TL;DR: In this paper, the authors compared theory and experiment for behavior very near critical points, and suggested that scaling laws provide a promising approach to understand phenomena near the critical point, but that they are by no means proved or disproved by the existing experimental data.

Scaling Laws for Dynamic Critical Phenomena
TL;DR: In this article, the usual static scaling laws are generalized to nonequilibrium phenomena by making assumptions on the behavior of time-dependent correlation functions near the critical point of second-order phase transitions.

Experimental investigations of critical phenomena
TL;DR: The experimental observation of critical phenomena in liquid-vapour, binary liquid, magnetic and other systems is discussed in this paper, and the results are presented in a normalized graphical form and integrated with data obtained from older techniques.

Transport Coefficients near the Liquid-Gas Critical Point
Leo P. Kadanoff,Jack Swift +1 more
TL;DR: In this paper, a perturbation theory for the determination of transport coefficients near the critical point is presented, which is based upon processes in which one transport mode decays into several low-wave-number modes.
