Query: Linear Response Theory with finite-range interactions   This review focuses on the calculation of infinite nuclear matter response
functions using phenomenological finite-range interactions, equipped or not
with tensor terms. These include Gogny and Nakada families, which are commonly
used in the literature. Because of the finite-range, the main technical
difficulty stems from the exchange terms of the particle-hole interaction. We
first present results based on the so-called Landau and Landau-like
approximations of the particle-hole interaction. Then, we review two methods
which in principle provide numerically exact response functions. The first one
is based on a multipolar expansion of both the particle-hole interaction and
the particle-hole propagator and the second one consists in a continued
fraction expansion of the response function. The numerical precision can be
pushed to any degree of accuracy, but it is actually shown that two or three
terms suffice to get converged results. Finally, we apply the formalism to the
determination of possible finite-size instabilities induced by a finite-range
interaction.
