HiGGS Calibration Survey

About

Survey by the HiGGS package of Poisson brackets between primary and secondary constraints for 192 modified gravity theories with curvature and torsion.

See HiGGS README.md and references therein for all details, conventions, notation and motivation.

Installation

1. Make sure you have installed HiGGS.
2. Download the survey:

   git clone https://github.com/wevbarker/HiGGS-calibration-survey
   cd HiGGS-calibration-survey
   tar -xzvf svy.tar.gz

3. Place the ./svy directory in the working directory of your Mathematica notebook.

Quickstart

The theory files ./svy/simple_spin_*.thr.mx contain all the physics. Everything under ./svy/node-* pertains to clocking.

The .thr.mx theory files use a conventions in which vanishing multiplier couplings (convention is A for "alpha" couplings and B for "beta" couplings) are appended to the file name, but only if they are not constrained by default.

Open a fresh notebook in the same directory as svy and run:

$Path~AppendTo~NotebookDirectory[];
Needs["xAct`HiGGS`"];
BuildHiGGS[];

You should end up in a HiGGS environment. To view the constraint and bracket structure of a given theory, such as the minimal spin-parity 1⁺ case with all (surveyed) multipliers active, try
