The problem of competition between different phases, especially superconductivity and charge density wave, has attracted a lot of attention recently in the context of high temperature superconductors. There are simpler systems, however, where such a competition has also unexpected effects such as the creation of marginal Fermi liquid states. In this talk I will discuss the physics of transition metal dichalcogenides such as TaSe₂ and NbSe₂ that are layered systems with anomalous properties that still remain to be understood.
