Ultrafast angle–resolved XUV photoemission reveals the time- and momentum-dependent electronic structure of 1T–TaS2, a hybrid Mott and charge-density-wave insulator. Both electronic orderings melt well before the lattice responds, suggesting that electronic correlations play a role not just in the Mott localization but in the CDW ordering as well.
