about mu* pseudo potential

Post by topgun »

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 when experimental value is not known- "how do we calculate Tc if we do not know mu* "

Thanks in advance.

Hi,

You can vary mu* between 0.1 and 0.2 and see how Tc changes (most systems have mu* between these limits). As an alternative, you can estimate mu* for your system using Morel-Anderson expression.
