Canonical Ensemble/Measure maximises differential entropy
Denote the so-called canonical ensemble as $\mu$ :
$$ \mu(dq,dp)=Z^{-1}_\beta e^{-\beta H(q,p)}dqdp. $$
(with say $p,q \in \mathbb{R}^{3N}$ for some $N\in \mathbb{N}$ and $Z_\beta$ the normalisation c …

Difference Between Molecular Dynamics and Kinetic Theory? Loschmidt's
I have heard Loschmidt's paradox described as "the laws of thermodynamics are time asymmetric because entropy always increases, but the underlying laws of physics are symmetric under time reversal." … Could someone explain the main difference between thermodynamics (is this the same as Kinetic Theory or Statistical Mechanics?) …

In the Langevin dynamics: neglecting inertia. A mathematician trying to understand physics t...
If we write the Langevin equation: for a particle with mass $m$, position $x$ and velocity $v$, with some damping coefficient $\gamma$,
$$ m dV(t)=-\gamma V(t)dt+dW(t) ,~~~~~~~dX(t)=V(t)dt.$$
Then as …
