MesoHOPS is a Python library for running simulations with the Hierarchy of Pure States (HOPS), a formally exact trajectory-based approach for solving the time-evolution of open quantum systems coupled to non-Markovian thermal environments. The main feature of MesoHOPS is the implementation of adaptive HOPS (adHOPS), an extension of the HOPS formalism that leverages the dynamic localization of excitations to construct an adaptive basis, allowing for O(1) - i.e. size invariant - scaling with the number of molecules.
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
