DESCRIPTION:Andrea Mann\, Laboratory for Ultrafast Microscopy and Electron
  Scattering\, ICMP - EPFL\nThe transition metal dichalcogenide tantalum di
 sulfide (TaS2)\, which shows a charge density wave (CDW)\, has been the su
 bject of numerous studies during the past years due to its intriguing comb
 ination of electron-electron and electron-phonon correlations. Timeresolve
 d ARPES and electron diffraction measurements have shown that below 200K T
 aS2 enters an insulating phase with features of both the Mott and the Peie
 rls mechanism. Furthermore\, superconducting phases can appear in TaS2 and
  related compounds under certain conditions\, opening the question of the 
 mechanism of superconductivity and its relation to (or competition with) t
 he CDW mechanism.
