In this work we introduce a method for modeling and characterizing non-markovianity due to temporally correlated fluctuating hamiltonians in the quasi-static DC/low-frequency limit and demonstrate its performance in simulation. While not fully general,
this limit captures many important forms of non-markovianity, such as non-markovian dephasing. Moreover, this demonstrates an essential first step in the development of models for non-markovianity arising from hamiltonians fluctating according to arbitrary noise spectra.
