Physics:Quantum matter/phase
A phase is a distinct form of matter with uniform physical properties. Different phases arise from changes in conditions such as temperature and pressure.
Description
Phases describe states of matter that are homogeneous and stable under given conditions. Transitions between phases occur when external parameters change.
Properties
- uniform properties
- depends on external conditions
- changes via phase transitions
Description
phase is a matter-scale concept used to organize how quantum theory describes atoms, particles, fields, condensed matter, plasma, or spacetime-related systems. In the Quantum Collection it is placed by scale so the reader can move from materials and molecules down to subatomic degrees of freedom.
Quantum context
At this scale, the relevant behavior is controlled by quantized states, interactions, conservation laws, and the way excitations or particles are observed. The concept is normally linked to measurable properties such as energy, momentum, charge, spin, spectra, scattering rates, or collective modes.
Role in the collection
This page provides a compact reference point for related pages in Book II. It should be read together with nearby matter-scale topics and the corresponding foundations in quantum mechanics.[1]
