is a spinor essentially the coeffients of the base kets of an abitrary state ket?
A spinor is a mathematical object used to describe spin of particles in quantum mechanics. It is a complex vector that contains information about the spin state of a particle.
A spinor is similar to a vector in that it contains components and can be transformed under rotations. However, it also has an additional phase factor that makes it different from a regular vector. It is also different from a tensor in that it transforms in a more complicated way under rotations.
In quantum mechanics, a state ket is a mathematical representation of a quantum state of a system. The coefficients of a state ket refer to the complex numbers that represent the different possible states of a particle's spin in a given measurement.
Spinors are used in physics to describe the intrinsic angular momentum (spin) of particles. They are also used to describe the symmetries of a system and to calculate probabilities of different spin states in a measurement.
No, spinors are also used in other branches of physics such as relativity and particle physics. In these fields, they are used to describe the behavior of spinors in curved space-time and to model the interactions of particles with spin.
