[Pw_forum] Question on epsilon.x

[Vidur Parkash]

Hi everybody

I was doing some computations on dielectric functions, and noticed a 
'shift' parameter that offsets the imaginary part of the dielectric function by some value.

I wanted to know why is the parameter needed anyway, and how do we decide what value is used
