Phase transitions as a research area investigates qualitative changes in the macroscopic state of matter or systems as control parameters such as temperature, pressure, or external fields are varied, with emphasis on critical phenomena, universality, and order-parameter behavior. It encompasses equilibrium and nonequilibrium transitions, including first- and second-order transitions, symmetry breaking, renormalization-group theory, and scaling laws. The field spans condensed matter physics, statistical mechanics, and interdisciplinary complex systems, using analytical, numerical, and experimental methods to characterize phase diagrams, critical exponents, collective excitations, and emergent structures, and to understand how microscopic interactions give rise to distinct thermodynamic or dynamical phases.
Similar to the widespread interest in graphite and diamond, there is growing interest in metastable phases, which have different physical properties than those of stable phases. However, processes to fabricate metastable-phase ...
