so for a large cell, we can use a small k-mesh to obtain a similar accuracy;
for example, when we calculate cubic diamond using the 1x1x1 conventional
cell,
we need a 5x5x5 M-P k-mesh, when we calculate the 5x5x5 supercell, the 1x1x1
K-mech is enough |

发帖数: 339 | 9 That is a propaganda article of their approach to
thermodynamics (so called axiomatic approach).
The mainstream view of thermodynamics among physicists is
that thermodynamics
should be derived from statistical physics, and the entropy
in stat mech.
is defined as S=k N log N, where N is the number of
microscopic states,
Shannon generalized the concept of microscopic state to
possible
states in communication, thus derived a similar formula for
"information".

发帖数: 42 | 11 I would say that it depend on your problem. If your problem is kind of
simple but unique (the available toobox or things like that can not handle
flexible), then like rossby said, do it yourself. Otherwise, like:
1. complex geometry;
2. complex equation; ...
better to use some software.
Actually I am not clear with what you say about PDE, there are thousands
of them and a lot of software for each group of them.

As an academic humor point of view:
MgB2 : Boy --- 美 --- Boy
BCS mech: electron -- phonon -- electron
(fermion) (boson) (fermion)
As we know, the phonon-electron scattering and
electron-elctron interaction cause the resitivity,
when they correlate together, scattering mainly
becomes internal which cause no TOTAL-monmentum
changing, (scattring between Cooper pair ect is
just higher order neglect |

发帖数: 53 | 13 Sure. To derive this formula only requires stat. mech. (the $\eta$ I mentioned
is just the mean occupation number for bosons/fermions) One derives the energy
density for each particle sepcies and then adds them up.
I mentioned cosmology b/c the formula you mentioned (energy
density for several particle species) often finds its application in
cosmology: e.g. when you want to consider the energy density of the
universe at a certain epoch, when there're photons, neutrinos, electrons... |

knows quite a bit about mechanical keyboards, this is a pretty decent deal.
The keyboard has been roughly $75 in the past but hasn't been for quite some
time. This keyboard was also unavailable for quite some time but it looks
like they're bringing it back since mech keyboard are gaining nothing but
popularity.
