Natalio Mingo's Legacy of Open-Source Codes—ShengBTE, almaBTE and QSCAILD

The availability of tools can have a significant impact on a field by benefiting the whole community. Among his many accomplishments, Dr. Natalio Mingo led the development of three open-source codes: ShengBTE, almaBTE and QSCAILD. ShengBTE is a software package that solves the space- and time-independent phonon Boltzmann transport equation for computing the lattice thermal conductivity of crystalline materials. almaBTE is a software package that solves the space- and time-dependent phonon Boltzmann transport equation for crystalline materials and inhomogeneous structures. QSCAILD is a python library that computes temperature-dependent effective 2nd and 3rd order interatomic force constants in crystals, including anharmonic effects, based on the quantum statistics of a harmonic model. We will review the development, functionality and impact of these codes. This presentation is in memory of Dr. Natalio Mingo.
