Exceptional points in Fermi liquids with quadrupolar interactions
Rui Aquino, Daniel G. Barci
We show the existence of non-Hermitian degeneracies, known as exceptional points, in the collective mode spectrum of Fermi liquids with quadrupolar interactions. Through a careful…

Two-dimensional Fermi liquid dynamics with density and quadrupolar interactions
Rui Aquino, Daniel G. Barci
We consider a Fermi liquid model with density-density as well as quadrupolar forward scattering interactions parametrized by the Landau parameters and . Using bosonizati…
