Ultrafast, correlated multidimensional shell dynamics of neon matrices after photoexcitation of an NO impurity: An MCTDH approach

► Quantum study of matrix response upon femtosecond photoecxitation of NO impurity. ► High-dimensional quantum propagation is performed using the MCTDH method. ► Mean field results overestimate vibrational coherences. ► Correlations lead to small, but measurable effects in simulated pump-probe spectra.
