Validity of Boltzmanns Equation and $H$-function theorem?
A while ago I came across a resource (which I have forgotten) on the validity of Boltzmann's equation. It talked about the fact that the Boltzmann's equation is valid at the extrema of the $H$-...

Wien on Temperature and Entropy
As far as I understand, Wien defines entropy, which he uses in his derivation, as
$$ S = \text{v} \int\limits_0^{\infty} \varphi(\rho, \nu) d \nu, $$
where $\text{v}$ is the volume occupied by ...

Ask for Frank Wilczek's notes on entropy and entanglement
I know that I am not asking a question on physics. My question is just about learning physics. I am studying entanglement entropy and find some lecture notes by Frank Wilczek
But I can only find the ...

Thermodynamics of binary symmetric channels
I am reading this very interesting paper:
http://m.iopscience.iop.org/1751-8121/41/40/402002/pdf/1751-8121_41_40_402002.pdf about thermodynamics of channels in information theory.
More generally, ...

Bolzmann entropy [duplicate]
The Boltzmann entropy is defined as the logarithm of the phase space volume
(E). Is there a reference, book, paper which shows where this definition comes and how it is equal to the phase space ...

Confusion regarding entropy, reference papers request
1.a In paragraph at Wikipedia/Entropy it is stated:
This is because energy supplied at a high temperature (i.e. with low entropy)
tends to be more useful than the same amount of energy

Reference paper to support information -- energy relation $\left(kT \ln2 \rm\frac{J}{bit}\right)\;.$
In answer to Maxwell's Demon Constant (Information-Energy equivalence) there is stated that one bit of information allows to perform $kT \cdot \ln2$ Joules of work. Which paper supports the thesis?...

Deriving an Expression for Entropy
How to derive an expression for entropy in form of
$S = \ln \Omega$
from the form
$\displaystyle{S = - \sum_i \; p_i \ln p_i}$ ?
That is the last formula taken as a definition of entropy.
Just a ...
