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.
Based on an experiment at CERN, a collaboration led by the Niels Bohr Institute, University of Copenhagen, can predict hitherto unchartered changes in the shape of nuclei.

In the context of quantum mechanics and information, "magic" is a key property of quantum states that describes the extent to which they deviate from so-called stabilizer states. Stabilizer states are a class of states that ...
A research team has successfully achieved an atomically controlled insulator-to-metal transition in iridate/manganate heterostructures. Their findings were recently published in Nature Communications.

Moiré superlattices are materials consisting of two layers stacked on top of each other with either a small rotational misalignment or a lattice mismatch between them. The Kondo lattice model, on the other hand, describes ...
Observations of preschool children in classrooms and playgrounds have uncovered new social phases in human movement. Employing ultra-wideband radio frequency identification (UWB-RFID) technology allows for the precise tracking ...
