Query: openMMF: a library for multimode driven quantum systems   OPENMMF is a numerical library designed to evaluate the Time-Evolution
Operator of quantum systems with a discrete spectrum, and driven by an
arbitrary combination of harmonic couplings. The time-evolution operator is
calculated as a multifrequency Fourier expansion, which results from expressing
the time-dependent Schr\"{o}dinger equation in the frequency domain (Ho, Chu
and Tietz, Ch. Phys. Lett 96, 464 (1983)). The library provides a generic tool
to study systems with arbitrary spectral composition, limited only by the
available computational resources. OPENMMF includes functionalities to build
dense and sparse matrix representations of the system Hamiltonian and various
functions to calculate physical quantities such as the micromotion operator and
time/phase average of state populations. The library uses a generalised notion
of dressed state for systems with polychromatic driving. In this paper, we
describe the design and functionality of OPENMMF, provide examples of its use
and discuss its range of applicability. The library is written in
object-oriented style Fortran90 and includes a set of wrappers for C++ and
Python.
