Electrons, pseudoparticles, and quasiparticles in one-dimensional interacting electronic systems
J. M. P. Carmelo, A. H. Castro Neto, N. M. R. Peres
We find the singular transformation between the electron operator and the pseudoparticle operators for the Hubbard chain. We generalize the concept of quasiparticle to one-dimensio…

Non-Linear Waves in Fermi Liquids
A. H. Castro Neto
I show that when non-linearities are taken into account the Landau theory of Fermi liquids predicts the existence of hyperbolic waves in fermionic systems. The zero sound is descri…
