Causal Set Generator and Action Computer

Understand

The causal set approach to quantum gravity has gained traction over the past three decades, but numerical experiments involving causal sets have been limited to relatively small scales.

• The software suite presented here provides a new framework for the generation and study of causal sets.
• Its efficiency surpasses previous implementations by several orders of magnitude.
• We highlight several important features of the code, including the compact data structures, the $O(N^2)$ causal set generation process, and several implementations of the $O(N^3)$ algorithm to compute the Benincasa-Dowker action of compact regions of spacetime.
