fluctuoscopy 0.2.1

A Python wrapper with extras for the FSCOPE program, written by Andreas Glatz

Calculate conductivity contributions of superconducting fluctuations.

A blazingly fast^TM Rust/Python port for the C++ FSCOPE program written by Andreas Glatz.

Installation

With Python >3.9 use

pip install fluctuoscopy

Usage

Calculate R(T) from the fscope function in SI units:

import fluctuoscopy
R, sigmas = fluctuoscopy.fscope(T, Tc, tau, tau_phi0, R0, alpha, tau_SO)

Where the inputs are floats or numpy arrays, and the outputs are an array of resistances and a dictionary of conductivity contributions, in SI units.

You can also do dimensionless calculations, returning conductivity contributions in units G0:

sigmas = fluctuoscopy.fluc_dimless(t, h, Tc_tau, Tc_tauphi)

These calculations have optimised Rust ports. To see other possible calculations use

fluctuoscopy.fscope_full({})

Where parameters are passed in as a dictionary, see the FSCOPE documentation for a full list of calculations and parameters.

Note that this uses a pre-compiled version of FSCOPE, we compiled for Windows x86, macos x86 and arm64, and linux x86. If you are on a different platform, you will have compile FSCOPE yourself.

Development and testing

For development/testing, clone the repo

git clone https://github.com/g-kimbell/fluctuoscopy

Then go inside the repo and install in editable mode

cd fluctuoscopy
pip install -e .

The project uses maturin, if you edit the Rust code or if you are on a particularly weird platform that we have not already compiled for, you will have to recompile the binaries then reinstall the module

pip install maturin
maturin build --release
pip install -e .

For testing install and run pytest

pip install pytest
pytest
