Abstract: We consider a Fermi liquid model with density-density as well as quadrupolar forward scattering interactions parametrized by the Landau parameters ${F}_{0}$ and ${F}_{2}$. Using bosonization and a decimation technique, we compute collective modes and spectral functions for a huge range of interactions, ranging from strong repulsion to strong attraction in either angular momentum channel. We present a dynamical phase diagram showing a region of parameters where the collective mode structure changes abruptly, possibly signaling a dynamical phase transition.
