Unifying temperature definition in atomistic and field representations of conservation laws

Y Chen - Proceedings of the Royal Society A, 2024 - royalsocietypublishing.org
In this work, a field representation of the conservation law of linear momentum is derived
from the atomistic, using the theory of distributions as the mathematical tool, and expressed …
