Dear all,
I'm doing the electron-phonon coupling calculation. I find that in the
source file *elphon.f90* it writes as follows:
*parameter (eps = 20.d0/13.6058d0/8065.5d0)*
*........*
*.......*
*.......*
*if (sqrt(abs(w2(nu)) .gt. eps ) then*
* lambda = gamma/3.1415926/w2(nu)/dosef*
*else*
* lambda = 0.0*
*.......*
*.......*
**
So I want to know why it sets *eps=20,* can we change the value of *eps*?
Best wishes!
