-Note that when using `HamEvo` with a time-dependent generator, its second argument `parameter` is not used and an arbitrary value can be passed to it. However, in case of time-dependent generator a value for `duration` argument to `HamEvo` must be passed in order to define the duration of the simulation. The unit of passed duration value $\tau$ must be aligned with the units of other parameters in the time-dependent generator so that the integral of generator $\overset{\tau}{\underset{0}{\int}}\mathcal{\hat{H}}(t){\rm d}t$ is dimensionless.
