Ultrafast gap dynamics upon photodoping the Mott-insulating phase of a two-dimensional organic charge-transfer salt

Konstantin Warawa, Yassine Agarmani, Harald Schubert +4

We investigate experimentally the ultrafast changes in the spectral response of the Mott insulator $\kappa$-(BEDT-TTF)${}_2$Cu[N(CN)${}_2$]Cl ($\kappa$-Cl) upon photodoping with intense excitati…
