Tracking the photoinduced dynamics of a dark excitonic state in single-layer WS via resonant Autler-Townes splitting
Angela Montanaro, Francesco Valiera, Francesca Giusti +10
Excitons in a monolayer transition metal dichalcogenide (1L-TMD) are highly bound states characterized by a Rydberg-like spectrum of discrete energy levels. Among these, states wit…
Ultrafast pump-probe phase-randomized tomography
Filippo Glerean, Enrico Maria Rigoni, Giacomo Jarc +6
Measuring fluctuations in matter's low energy excitations is the key to unveil the nature of the nonequilibrium response of materials. A promising outlook in this respect is offere…
Dynamics of non-thermal states in optimally-doped revealed by mid-infrared three-pulse spectroscopy
Angela Montanaro, Enrico Maria Rigoni, Francesca Giusti +13
In the cuprates, the opening of a d-wave superconducting (SC) gap is accompanied by a redistribution of spectral weight at energies two orders of magnitude larger than this gap. Th…
Manipulation of Charge Delocalization in a Bulk Heterojunction Material Using a Mid-Infrared Push Pulse
Angela Montanaro, Kyu Hyung Park, Francesca Fassioli +3
In organic bulk heterojunction materials, charge delocalization has been proposed to play a vital role in the generation of free carriers by reducing the Coulomb attraction via an…
