A new approach for few-femtosecond time-resolved photoelectron spectroscopy in condensed matter that balances the combined needs for both temporal and energy resolution is demonstrated. Here, the method is designed to investigate a prototypical Mott insulator, tantalum disulphide (1T-TaS2), which transforms from its charge-density-wave ordered Mott insulating state to a conducting state in a matter of femtoseconds. The signature to be observed through the phase transition is a charge-density… Expand
