We consider the possibility of the quantum vacuum states in f(R, T) gravity. Particularly,
we study the Bogoliubov transformations associated to different vacuum states
for some f(R, T) models. The method consists of fixing the f(R, T) free parameters
by requiring the Bogoliubov coefficients to be minimized. In such a way, the particle
production is related to the value of the Hubble parameter and also the given f(R, T)
model.
