Abstract
We present the SpinParser open-source software [ https://github.com/fbuessen/SpinParser ]. The software is designed to perform pseudofermion functional renormalization group (pf-FRG) calculations for frustrated quantum magnets in two and three spatial dimensions. It aims to make such calculations readily accessible without the need to write specialized program code; instead, custom lattice graphs and microscopic spin models can be defined as plain-text input files. Underlying symmetries of the model are automatically analyzed and exploited by the numerical core written in C++ in order to optimize the performance across large-scale shared memory and/or distributed memory computing platforms.
Author comments upon resubmission
I am resubmitting a revised version of the manuscript “The SpinParser software for pseudofermion functional renormalization group calculations on quantum magnets”. In this revised manuscript, I have made changes to address the referees’ comments and suggestions, which have led to a substantial improvement in the documentation of the software. Detailed responses to each referee report are provided separately via the “Reply to the above Report” functionality on the website.
An overview of all the changes in the updated manuscript and the codebase is provided below.
Sincerely,
Finn Lasse Buessen
List of changes
Changes to the manuscript:
- In Sec. 2 (“Scope of the software”) below Eq. (4) and in Sec. 5.4 (“Output data”), short remarks to clarify that spin operators are defined in the local reference frame were added. In Section 5.3 (“Definition of spin interactions”), a paragraph to clarify the definition of spin operators in their local frame of reference was added.
- In Sec. 5.1 (“Structure of a task file”), a paragraph to provide instructions for performing generalized spin-S calculations was added.
Changes to the codebase:
- A separate documentation for the Python tools for data postprocessing was added to the codebase and made available at [https://fbuessen.github.io/SpinParser/doc-python].
- In the “Evaluate SpinParser output and measurements” section of the README, an extra paragraph and example code were added to illustrate the calculation of correlation functions which may be relevant to neutron scattering experiments.
- In the “Prepare a task file” section of the README, a paragraph was added to provide instructions for generalized spin-S calculations.
- In the “Prepare a task file” section of the README, two short remarks were added to clarify the definition of spin operators in their local frame of reference.
