Dynamical control of Coulomb interactions and Hubbard bands in monolayer 1T-TaS${}_2$

Niklas Notter, Markus Aichhorn, Anna Galler

Monolayer 1T-TaS${}_2$ hosts a star-of-David charge-density wave (CDW) that stabilizes a low-temperature Mott-insulating state. Recent time-resolved spectroscopies indicate a couplin…
