  We employ Landau's theory of normal Fermi liquids to study the quasiparticle
interaction in nuclear matter in the vicinity of saturation density. Realistic
low-momentum nucleon-nucleon interactions evolved from the Idaho N3LO chiral
two-body potential are used as input potentials. We derive for the first time
exact results for the central part of the quasiparticle interaction computed to
second order in perturbation theory, from which we extract the L=0 and L=1
Landau parameters as well as some relevant bulk equilibrium properties of
nuclear matter. The accuracy of the intricate numerical calculations is tested
with analytical results derived for scalar-isoscalar boson exchange and
(modified) pion exchange at second order. The explicit dependence of the Fermi
liquid parameters on the low-momentum cutoff scale is studied, which provides
important insight into the scale variation of phase-shift equivalent two-body
potentials. This leads naturally to explore the role that three-nucleon forces
must play in the effective interaction between two quasiparticles.
