[′fāz·ər]
(physics)
A rotating line used to represent a sinusoidally varying quantity; the length of the line represents the magnitude of the quantity, and its angle with the x-axis at any instant represents the phase.
Any quantity (such as impedance or admittance) which is a complex number.
(solid-state physics)
A low-energy collective excitation of the conduction electrons in a metal, corresponding to a slowly varying phase modulation of a charge-density wave.
