Here, dynamical light squeezing is observed in the emission from two coupled weakly nonlinear populations of exciton-polaritons through ultrafast time-resolved second-order correlation measurements. Full quantum simulations link the squeezing to the

Transient absorption spectra of C60 mols. trapped in cryogenic rare gas matrixes and dissolved in room temp. toluene were measured with a time resoln. of 90 fs. An absorption build-up with a characteristic rise time of 200 fs is measured, which is so

The dynamics of non-polar electronic solvation has been studied on a model system consisting of NO-doped solid Ar. Excitation of the lowest Rydberg state A(3ss) of NO leads to formation of an electronic 'bubble', which has been studied by femtosecond

The ultrafast production and decay of carbenes from the diphenyldiazomethane precursor in isooctane has been investigated by femtosecond transient absorption spectroscopy. Diphenylcarbene is produced in less than 300 fs in a singlet state. It then un

We report the femtosecond nuclear dynamics of an electronic ‘bubble’ in solid H2. The bubble formation results from the impulsive excitation of the lowest Rydberg state A2Σ+ (3sσ) of the NO impurity by a UV femtosecond pulse. The evolution of t

We follow the ultrafast dynamics of the medium response to impulsive Rydberg state excitation of an NO molecule trapped in solid argon using a femtosecond fluorescence depletion pump-probe technique. Our results show that the cage expands by undergoi

The dynamics of Rydberg states in condensed matter is still a field to be unravelled. The radius of low-n Rydberg states is comparable to the nearest neighbour distance in rare gas solids. Consequently, following photoexcitation of such states in a s

The intramol. energy relaxation processes of UV-excited C60 mols. embedded in Ar crystals were studied by picosecond fluorescence studies and femtosecond pump-probe absorption spectroscopy. The various internal energy relaxation steps are clearly ide

Excitation of the A(3ss) Rydberg state of NO trapped in an H2 crystal leads to the electronic bubble formation around the NO impurity, resulting in an increase of 0.9 .ANG. of the ground state cage radius. Its dynamics was followed in real-time by fe
