Region in a substance throughout which all physical properties are essentially uniform; region of material that is chemically uniform, physically distinct, (often) mechanically separable.
It's a distinct phaseofmatter with no true parallels in anything else you see in everyday life.

In this regime, our atomic gas corresponds to a phaseofmatter where Maxwell electrodynamics is replaced by axion electrodynamics: a 3D topological insulator.

Quantum phase transitions take place between distinct phasesofmatter at zero temperature.

This explained the new phaseofmatters and was anything but welcome information, but there was no help for it.
(Physical chemistry) a distinct state of matter in a system; matter that is identical in chemical composition and physical state and separated from other material by the phase boundary.
