Résumé

We discuss the spectral signatures of strong electronic correlations and electron-phonon interactions in two representative low-dimensional systems. In the 2D compound 1T-TaSe₂ a charge-density-wave (CDW) induces a narrowing of the conduction band, which triggers a surface metal-insulator (M-I) transition and the disappearance of the quasiparticle (QP) features. In the 1D blue bronze K_0.3MoO₃ strong interaction with the lattice lead to pseudogapped polaronic lineshapes, and the large mass renormalization masks the signatures of electronic correlations.
