A spinor representation is a representation of a Spin group, or infinitesimally of a Special orthogonal Lie algebra, constructed from a Clifford algebra. In even dimensions it can split into two chiral spinor representations.
The term "spin representation" is commonly used in the context of quantum mechanics and refers to a mathematical framework for describing the intrinsic angular momentum (spin) of quantum particles. Spin is a fundamental property of quantum particles like electrons, protons, neutrons, and other elementary and composite particles. ### Key Elements of Spin Representation: 1. **Quantum States**: Spin states are represented as vectors in a Hilbert space.
