Dark matter

Greetings, do you know the best way to calculate the thermal conductivity of a gas of weakly interacting massive particles?

The force is pair_style hybrid as a combination of gravitational (using coul/cut) and an empirical function for the weak force using table with spacing 10^-18 ft.

Also, does anybody have a data file of interstellar space equilibrated in the NPT ensemble? I think that (1000 km)^3 should be enough: I know that simulating a bigger one would be no easy matter.

Lastly, do you know whether LAMMPS can be compiled on the D-Wave Two? Although I don’t have a quantum Lagrangian implemented yet, I’m pretty sure that a quantum computer can only improve the results.

Thanks a bunch,

K

10^-18ft?

I think I can hazard a guess to that question:
Nope

"ft" ​this is probably a typo and ​it was likely meant to be "pc".

​hmm... looking at the d-wave homepage, it looks like it use a RESTful API
with libraries in C++ and Python, so that would make it compatible, but
you'd have to get LAMMPS to run in the cloud first.​ any volunteers to set
up a lammps-in-the-cloud server (CLLAMMPS)?

Is this a periodic system? pair coul/cut might not be a good choice.
Check the other available pair styles and coulombic

​just checked with one of my text books and there it says:

​Space is big. Really big. You just won't believe how vastly, hugely,
mind-bogglingly big it is. I mean, you may think it's a long way down the
road to the chemist, but that's just peanuts to space.

​so there is nothing about periodicity.​

​axel.​

​p.s.: you may have noticed, that there are some anomalies in the
time-space-continuum on a certain day of the year. perhaps this was one of
them?​

Also, be sure to use the “units startrek” command with these

kind of cosmological models.

As a serious aside, I’ve heard about cosmological codes

which solve for long-range gravitation using FFTs, similar
to MD codes, which means they do in fact treat the
universe as periodic.
