Mantid is a framework for the reduction and analysis of neutron and muon scattering data. It provides a collection of algorithms for data processing, visualization tools, and interfaces for instrument scientists and users at neutron and muon facilities worldwide.

Optional GUI extensions such as python-mslice and python-shiver appear in the Workbench Interfaces menu when installed alongside Mantid. Script libraries like python-mvesuvio can be imported in Workbench's script editor.

QuTiP is a library for simulating the dynamics of closed and open quantum systems. It aims to provide numerical simulations of a wide variety of quantum mechanical problems, including those with Hamiltonians and/or collapse operators with arbitrary time-dependence, commonly found in a wide range of physics applications.

Shiver (Spectroscopy Histogram Visualizer for Event Reduction) is a desktop application for examining Time of Flight inelastic neutron data from single crystal, direct geometry experiments. It integrates with Mantid Workbench and appears in the Interfaces menu when both packages are installed.

MVesuvio provides optimized analysis procedures for neutron scattering data from the VESUVIO spectrometer. It is a script library meant to be imported in Mantid Workbench's script editor (import mvesuvio as mv), not a GUI application.

TeNPy is a Python library for the simulation of strongly correlated quantum systems with tensor networks.

The philosophy of this library is to get a new balance of a good readability and usability for new-comers, and at the same time powerful algorithms and fast development of new algorithms for experts. For good readability, we include an extensive documentation next to the code, both in Python doc strings and separately as "user guides", as well as simple example codes and even toy codes, which just demonstrate various algorithms (like TEBD and DMRG) in ~100 lines per file.

This package provides common Qt GUI elements for authenticating with ONCat (ORNL Neutron Catalog), including login dialogs and session management widgets.

Euphonic is a Python package for calculating phonon bandstructures and simulating inelastic neutron scattering (INS) from force constants. It can read output from CASTEP and Phonopy and calculate phonon frequencies, eigenvectors, and structure factors.

This package provides a tool for performing slices and cuts of multi-dimensional data produced by Mantid.

PyCifRW provides support for reading and writing CIF (Crystallographic Information File) format files. CIF is the standard format for crystallographic data exchange endorsed by the International Union of Crystallography.

Cytnx is a tensor network library designed for quantum physics simulations using tensor network algorithms, offering the following features:

• Most of the APIs are identical in C++ and Python, enabling seamless transitions between the two for prototyping and production.

• Cytnx APIs share very similar interfaces with popular libraries such as NumPy, SciPy, and PyTorch, minimizing the learning curve for new users.

• Cytnx supports multi-device operations (CPUs/GPUs) directly at the base container level. Both the containers and linear algebra functions share consistent APIs regardless of the devices on which the input tensors are stored, similar to PyTorch.

• For algorithms in physics, Cytnx provides powerful tools such as UniTensor, Network, Symmetry etc. These objects are built on top of Tensor objects, specifically aiming to reduce the developing work of Tensor network algorithms by simplifying the user interfaces.

This library is based on papaer - The Cytnx library for tensor networks; Kai-Hsin Wu, Chang-Teng Lin, Ke Hsu, Hao-Ti Hung, Manuel Schneider, Chia-Min Chung, Ying-Jer Kao, Pochung Chen; https://doi.org/10.21468/SciPostPhysCodeb.53-r1.0.

This package provides a Python client for ONCat, the Oak Ridge National Laboratory Neutron Catalog. ONCat is a data catalog service for neutron scattering facilities.

Brille is a C++ library for symmetry operations and linear interpolation within an irreducible part of the first Brillouin zone. It provides Python bindings via pybind11 for use in phonon calculations and inelastic neutron scattering simulations.

This package provides the IUCr (International Union of Crystallography) core CIF dictionary and supplementary dictionaries which COMCIFS manages. Dictionary definitions are described using DDLm attributes, which are themselves described in 'ddl.dic'.

This package provides Python wrappers for Fortran routines used to perform Bayesian analysis on quasi-elastic neutron-scattering data. The original Fortran code was written by Dr. Devinder Sivia in the 1980s.

QuickBayes provides Bayesian analysis tools for analyzing neutron scattering data. It is designed for use with the Mantid framework for neutron and muon data analysis.

pkg-config is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler options on the command line so an application can use gcc -o test test.c `pkg-config --libs --cflags glib-2.0` for instance, rather than hard-coding values on where to find glib (or other libraries). It is language-agnostic, so it can be used for defining the location of documentation tools, for instance.

pkgconf is a program which helps to configure compiler and linker flags for development libraries. It is similar to pkg-config from freedesktop.org. libpkgconf is a library which provides access to most of pkgconf's functionality, to allow other tooling such as compilers and IDEs to discover and use libraries configured by pkgconf.

Plan 9 from User Space (aka plan9port) is a port of many Plan 9 programs from their native Plan 9 environment to Unix-like operating systems.

drawterm is a client for connecting venerable systems to Plan 9 systems. It behaves like a Plan 9 kernel and will attempt to reconstruct a Plan 9 terminal-like experience from a non-Plan 9 system.

Diod is a multi-threaded, user space file server that speaks 9P2000.L protocol.

9pfs mounts a file system using the 9P protocol. It is a replacement for 9pfuse from plan9port.
