query about mustar [ ?*]

Post by topgun »

Dear Roxana Margine,

While calculating superconducting transition temperature Tc, how do we give the value of mustar [ ?*].By ELIASHBERG-MIGDAL formalism.
It is usually said that it is kept between 0.15 and 0.10
But Can we go below 0.10 [?*<0.10] ?

Thanks in advance.

regards

Hi,

You can specify it in the input file as muc. The default value is 0. For most materials it is something between 0.1 and 0.2, but you can chose whatever value you want.

Best,

Dear roxana,

Thank you for the reply.
Are there experimental value of mustar [ ?*] for a material with which we can compare?
what should be the ideal criteria to take the input value of mustar [ ?*] for a material.
I work with ELK which have default value as 0.15.
