Spinors: A Mathematica package for doing spinor calculus in General Relativity

Abstract

The "Spinors" software is a "Mathematica" package which implements 2-component spinor calculus as devised by Penrose for General Relativity in dimension 3+1. The "Spinors" software is part of the "xAct" system, which is a collection of "Mathematica" packages to do tensor analysis by computer. In this paper we give a thorough description of "Spinors" and present practical examples of use.

12 pages, one figure. Typos corrected and references added. To appear in Computer Physics Communications
