Substitute α for λ in cell 3.7
amybug opened this issue · comments
Hey Andy ... Thank you so very much for these analyses! I have the smallest question about the text accompanying the plot of vs. α. The factor g for triangular lattice is sqrt(3)/2 = 0.866 so g triangular < g square = 1.
I believe the comment above the plot says "gsqu<gtri". More important, everything good in the plot, yes? E.g for the same value of λ , α would indeed be shifted to the right for the triangular lattice as compared with the square lattice ... so these data just don't have the same value of λ ... yes?
Hi Amy, thanks for catching this! I think I just got this inequality wrong, since it's actually in the case where gtri<gsqu that we would see the triangle data points shift to the right compared to square. Everything should still look okay.
Great, Andy! (And Celia!) That the graphs are correct is the main thing
... and you have assured me they are.
It is good to see this rising trend in <f> with alpha and to see, perhaps,
a small effect of lattice. My goal is to get you the missing N_p = 36 (and
more N_p = 100) data today, so that whenever this gets to the top of your
TODO list, there is another alpha value to add to the graph. (It will
become the second lowest, maybe?)
Do you think you want an ultra-small value of alpha? One with, say, 9
pins? The fact that triangular lattices have systematically lower values
of <f> than square suggests this is a real trend. But, one expects
geometry to not matter in the limit of small alpha.
So do think the difference between <f> = 0.0046 and 0.0049 is just
uncertainty? Do you want a 9 pin simulation run?
Take care,
Amy

I think a 9-pin run as a point of comparison might be really useful if that's not too difficult!
Hi Andy,
Sorry ... getting back to your issue reports and emails after a while.
I will put in fewer pins for 230 particles. Also, with the Sweep runs
being done (currently) at 512 particles, runs with 36 pins are roughly
like 16 pins for 230 particles. So it might be smart to do 16 pins as our
dilute-pin runs. I'll get them on the fiji queue today.
Take care,
Amy

Hi Andy and Celia,
Oops, nvm ... you already *have* 16 pin data? 500 seeds for squ and tri
lattices were put on Google Drive sometime in Week 3 of Summer '20. You
created force histograms, z_c, and many more plots using them! I'll do 9
pins :-)
Take care,
Amy
