In physics, disordered systems are physical systems whose microscopic constituents (e.g., atoms, spins, impurities, or structural units) lack translational or orientational long-range order and are characterized by randomness in parameters such as positions, couplings, or local potentials. This quenched or annealed disorder crucially affects thermodynamic, transport, and dynamical properties, leading to phenomena such as Anderson localization, glassy dynamics, and complex energy landscapes. Disordered systems are modeled using probabilistic descriptions of disorder realizations and ensemble averages, often requiring techniques from statistical mechanics, random matrix theory, and renormalization group methods to analyze emergent macroscopic behavior and phase transitions in the presence of randomness.
Water molecules do not simply swirl around in complete disorder; they can form certain preferred structures. This scientific fact is often presented in entirely unscientific ways. For example, when people speak of an alleged ...

Electronic nematicity is a phase of some crystalline solids in which electrons' collective properties, such as charge or spin densities, organize themselves into ordered patterns, lowering the crystal's rotational symmetry. ...

Some materials behave unexpectedly. They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, ...

Glass appears to be a solid, but in theory it sometimes behaves more like an extremely slow liquid. Physicists in Utrecht now show that glass-like structures can also exist in equilibrium, which is something many theories ...

"Glass" has a unique and distinct meaning in physics—one that refers not just to the transparent material we associate with window glass. Instead, it refers to any system that looks solid but is not in true equilibrium and ...
