Title: Module "calculatePlasmaFrequency"
Post by: sukhito teh on April 6, 2025, 15:33

Dear developers and users,
Does the function calculatePlasmaFrequency returns plasma frequency or square of plasma frequency? The formula in documentation https://docs.quantumatk.com/manual/Types/OpticalSpectrum/OpticalSpectrum.html#opticalspectrum-c (https://docs.quantumatk.com/manual/Types/OpticalSpectrum/OpticalSpectrum.html#opticalspectrum-c) uses ω², but the return value has unit of energy. Thank you for your attention.

The function returns the plasma frequency, i.e. the square root of the expression in the documentation.

If you want to compute plasma frequencies, I recommend turning symmetries off, it seems to be unreliable currently, we are looking into a fix.
