DRalgo is an algorithmic implementation that constructs an effective, dimensionally reduced, high-temperature field theory for generic models. The corresponding Mathematica package automatically performs the matching to next-to-leading order. Public release of https://arxiv.org/abs/2205.08815.
DRalgo can be installed as a Wolfram Paclet by running one of the following commands in Mathematica:
PacletInstall["DRalgo/DRalgo"]PacletInstall["https://github.com/DR-algo/DRalgo/releases/latest/download/DRalgo.paclet"]Note: Ensure that all dependencies of DRalgo are installed. Refer to the Requirements section for details.
DRalgo can also be installed manually by cloning the repository into the Applications folder within either the base or user-specific Mathematica Applications directory. These directories store Mathematica packages and can be located by evaluating the variables $BaseDirectory and $UserBaseDirectory in a Mathematica session. To identify these directories, run the following commands in Mathematica:
Print["Base Directory: ", FileNameJoin[{$BaseDirectory, "Applications"}]]
Print["User Base Directory: ", FileNameJoin[{$UserBaseDirectory, "Applications"}]]For versions of Mathematica prior to 14.1, the typical paths for these directories are as follows:
Linux
/usr/share/Mathematica/Applications~/.Mathematica/Applications
macOS
~/Library/Mathematica/Applications
Windows
C:\ProgramData\Mathematica\ApplicationsC:\Users\<username>\AppData\Roaming\Mathematica\Applications
Starting with Mathematica 14.1, these directories have been renamed to include "Wolfram" instead of "Mathematica." For example, on macOS, the path becomes:
~/Library/Wolfram/Applications
Ensure that the DRalgo package is placed in the appropriate directory for your system and Mathematica version.
DRalgo is written in the Wolfram Mathematica language and relies on the external package GroupMath, available here:
- Mathematica: versions 12.x, 13.x, and 14.x
- GroupMath: version 1.1.3
GroupMath can be installed manually from the link above or automatically by setting the following flag before loading DRalgo in Mathematica:
DRalgo`DRalgo`$InstallGroupMath = True;By default, DRalgo will automatically load GroupMath when needed. If you wish to disable automatic loading, set the following flag instead:
DRalgo`DRalgo`$LoadGroupMath = False;Since GroupMath is an external package, any use of the model-creation features in DRalgo should be accompanied by a corresponding citation of: R. M. Fonseca, GroupMath: A Mathematica package for group theory calculations, Comput. Phys. Commun. 267 (2021) 108085 [2011.01764]
Once the DRalgo package is installed, it can be loaded in Mathematica by executing the following command:
<<DRalgo`DRalgo`This command initializes the package, making its functions and features available for use within your Mathematica session.
To explore how DRalgo works in practice, we recommend reviewing the provided examples.
These examples can be executed directly within a Mathematica notebook or via Wolframscript. Wolframscript enables the execution of Wolfram Language scripts without requiring a full Mathematica installation, offering the core computational capabilities of Wolfram Mathematica.
To run an example file using Wolframscript, use the following command:
$ wolframscript -file examples/xsm.mEnsure that an active WolframKernel is available for the above command to work.
Users are encouraged to contribute their own models to the community by submitting the model file through the Issue Tracker on GitHub. Submitted models will undergo verification before being added to the official model repository.
When submitting a model, please include a reference to a relevant paper or provide the explicit Lagrangian in an accompanying Mathematica notebook to ensure clarity and reproducibility.
