A generic tool to evaluate second quantization

Abstract

Second quantization has been widely used in quantum mechanics and quantum chemistry, which is trivial and error-prone for researchers. Fortunately it is a good candidate for automatic evaluation with its simple, trivial and intrinsic iterative nature. This article presents an automatic and generic tool for these kinds of evaluations. We believe it could be a helpful tool for scientists, and hope the idea of automatic evaluation could be generalized to other equation derivations in the future.
