spinor
spin·or S0642800 (spĭn′ər)n. A mathematical object associated with group representations, often used in theoretical physics to model certain topological properties of space. Spinors resemble vectors but change sign (that is, they are multiplied by -1) when rotated 360 degrees.

spinor[′spin·ər] (mathematics) A vector with two complex components, which undergoes a unitary unimodular transformation when the three-dimensional coordinate system is rotated; it can represent the spin state of a particle of spin ½. More generally, a spinor of order (or rank) n is an object with 2 n components which transform as products of components of n spinors of rank one. A quantity with four complex components which transforms linearly under a Lorentz transformation in such a way that if it is a solution of the Dirac equation in the original Lorentz frame it remains a solution of the Dirac equation in the transformed frame; it is formed from two spinors (definition 1). Also known as Dirac spinor. Spinor a mathematical quantity whose transformation from one coordinate system to another is governed by a special law. Spinors are used for various problems in, for example, quantum mechanics and representations of groups. SPINOR
