A summary of comparison of dynamic properties between the hybrid (current), fluctuating hydrodynamics, and generalized Langevin approaches. Abbreviations, MBD: Maxwell-Boltzmann distribution.

Method	VACF	Diffusion
Hybrid	Follows (i) an exponential decay at short times; (ii) an algebraic decay over long times (translational: t^−3/2 & rotational: t^−5/2)	Obey Stokes-Einstein (translation) and Stokes-Einstein-Debye (rotation) relations
Fluctuating hydrodynamics [22]	Follows (i) an exponential decay at short times; (ii) an algebraic decay over long times (translational: t^−3/2 & rotational: t^−5/2)	Obey Stokes-Einstein (translation) and Stokes-Einstein-Debye (rotation) relations
Generalized Langevin dynamics [30]	Follows (i) a stretched exponential decay at short times; (ii) an algebraic decay over long times (translational: t^−3/2 & rotational: t^−5/2)	Obey Stokes-Einstein (translation) and Stokes-Einstein-Debye (rotation) relations, with scaling factors
