Michelson-Morley Experiments Revisited and the Cosmic
... k = 0 in both the gas-mode and vacuum mode, and so in both modes a null effect is predicted. However in the new physics, as we derive below, k = n(n 2 − 1) where n is the dielectric constant of the gas in which the interferometer operates and this gives k = 0 only for the vacuum (n = 1) mode.

Quantum refrigerators and the third law of thermodynamics
... The rate of temperature decrease of a cooled quantum bath is studied as its temperature is reduced to absolute zero. The third law of thermodynamics is then quantified dynamically by evaluating the characteristic exponent ζ of the cooling process dTdt(t) ∼ −T ζ when approaching absolute zero, T → 0. ...
