LFXC = .TRUE. | .FALSE. 

Default: LFXC = .FALSE.

Description: LFXC enables the local exchange-correlation kernel in TD-DFT and TDHF calculations.


The local exchange-correlation kernel is determined via [1]

fxcloc(𝐫,𝐫)=δ2{EcDFT+(1cx)ExDFT}δρ(𝐫)δρ(𝐫),

where cx is the fraction of the exchange interaction set by AEXX.
