- adj. Describing any closed system of constant volume which is thermally isolated from its surroundings, and whose total energy is constant and is known
from The Century Dictionary and Cyclopedia
- In statistical mechanics, of or pertaining to a distribution in phase such that all the systems of an ensemble have the same energy.
Sorry, no etymologies found.
Per Shang-Keng Ma, an entropy can be defined as the logarithm of the phase-space volume explored by the system over a given timescale; the states relevant for thermodynamics (mumble mumble microcanonical mumble mumble) would be the decategorification of the states used at the statistical-mechanical level.
Indefinitely many distinct microcanonical ensembles of a token volume of gas molecules can yield the same mean molecular kinetic energy.
One might then still conjecture that if the system is quasi-ergodic, the only continuous stationary distribution is microcanonical.
In other words, the only stationary probability with fixed total energy is the microcanonical distribution. Ïmc = Î´ (H (x) ’ E), where Î´ is Dirac's delta function.
