Dear Lucas
TDDFPT is definitely a linear-response method. If you want to read
something, there is plenty of references in this file

Quoting Lucas Nicolás Lodeiro Moraga <lucas.lode...@ug.uchile.cl>:
Hello all,
I am introducing myself into the Time Dependent DFT to compute UV-Vis
spectroscopy. Among the literature, I find that there are two
approximations for that, the Linear Response and the Real Time propagation
approaches...
But, in some codes like CP2K an Quantum ESpresso, the implemented methods
refer to TD-DFPT, which seems to be the linear response approach, but is
not clear to me if this is ok or wrong...
Does somebody know the differences and can give some insight or "simple"
references to clarify me?
