I meant "theory" related to Fermi nesting function.

Dear Roxana & Ponce,

can Roxana or Ponce refer the "theory related to Fermi nesting function". Any publication where " Fermi nesting function" is either plotted or discussed would be greatly appreciated.

Thanks in advance.

Dear all,
can the developers refer the "theory related to Fermi nesting function". Any publication where " Fermi nesting function" is either plotted or discussed would be greatly appreciated.

Dear all,
How do we choose: which "equations of state" suits my material for "pressure vs volume plot".
e.g. Murnaghan EOS OR Birch-Murnaghan EOS OR Birch-Murnaghan. How do one decide which is most suitable.

Dear Roxana ma'am,
Thank you for the suggestions. These were really helpful.

Dear Roxana and ponce, How do we take the value of mu* if we are to predict the transition temperature of a superconductor which does not exist and hence its experimental Tc is unknown. when the experimental value of is Tc known, we can just adjust the value of mu* to calculate the right Tc. but ...

dear all,

while trying to find the (alpha)^2 , I have obtained a 0/0 data point (undefined) in my graph i.e a discontinuity in my continuous graph. what is the way out of it.

thanks in advance.

Dear all, What is potential mixing? If for example we take GGA [for our calculations in input file] does the potential remains same in character like GGA [or total potential] or evolve into something else after potential mixing. Does 'potential mixing' happen in DFPT based calculations. Thanks in ...

Dear roxana maam,

Thank you for the reply.
But, is there any way by which I can know the components of (say) acoustic phonons or optical phonons in the phonon DOS and eliasberg function plots. i.e Longitudinal and transverse acoustic phonons [ LA and TA phonons].

THANKS IN ADVANCE

Dear roxana,

While comparing phonon DOS and Eliasberg spectral function :: how do we know "which part of the curve represent which mode of vibration" ?. If the "mode of vibration" is optical or acoustic or is a component of these two.

Thanks in advance
