Extended Data Fig. 8: Role of Coulomb correlations on the subcycle delay.
From: Attosecond clocking of correlations between Bloch electrons
Computed subcycle delay for bulk (orange) and monolayer (blue) WSe2 as a function of the exciton binding energy resulting from a Coulomb interaction suppressed artificially, while keeping all other parameters fixed. Orange and blue dashed vertical line: exciton binding energy E1s of bulk (E1s = 60 meV) and monolayer (E1s = 295 meV) WSe2, respectively. The arrow marks the subcycle-delay shift of 2.1 fs due to increased excitonic binding.
