Non Fermi Liquid behavior and disorder in BaVS$_3$

In strongly correlated BaVS$_3$, the interplay between a wide one-dimensional $d_z^2$ band and the localized $e_g$ electrons leads to a wealth of electronic phases. In this work we investigate the high pressure non-Fermi liquid (NFL) phase of BaVS$_3$ by means of transport measurements, focusing on the influence of disorder, introduced by fast electron irradiation and sulfur deficiency. Our results are interpreted within a novel scenario in which quasi-one dimensional 2$k_F$-CDW fluctuations are responsible for the NFL behavior.\footnote{N.
