FHD: Equipartition theorem is satisfied.
The particle mass m is augmented by an added mass
m0/2, to account for compressibility. |
GLD: Equipartition theorem is satisfied.
When the thermostat adheres to the equipartition theorem, the characteristic memory
time in the noise is consistent with the inherent time scale of the memory
kernel. |

VACF |
FHD: The translational and rotational
VACFs of the particle follow an exponential decay,
exp(−ζ(t)t/M)
and
exp(−ζ(r)t/I)),
respectively, at short times, and a power-law decay, a0
(t/τν)−3/2
and b0
(t/τν)−5/2,
respectively at long times. The value of a0 and
b0 agrees with Hauge and Martin-Löf
[10]. |
GLD: The translational and rotational
VACFs of the particle follow a stretched exponential decay,
exp{−(t/τν)3/2},
at short times, and a power-law decay, a0
(t/τν)−3/2
and b0
(t/τν)−5/2,
respectively, at long times. The value of a0 and
b0 differs from those predicted by Hauge and
Martin-Löf [10]. |

MSD |
FHD: In the diffusive regime,
translational and rotational MSDs obey Stokes-Einstein and Stokes-Einstein-Debye
relations, respectively. |
GLD: In the diffusive regime,
translational and rotational MSDs obey Stokes-Einstein and Stokes-Einstein-Debye
relations, with scaling factors of 3 and 102.54, respectively. |
