Ab-initio calculation of all-optical time-resolved calorimetry of nanosized systems: Evidence of nanosecond-decoupling of electron and phonon temperatures
F. Banfi, F. Pressacco, B. Revaz +4
The thermal dynamics induced by ultrashort laser pulses in nanoscale systems, i.e. all-optical time-resolved nanocalorimetry is theoretically investigated from 300 to 1.5 K. We rep…
Ultrafast insulator-to-metal phase transition as a switch to measure the spectrogram of a supercontinuum light pulse
Federico Cilento, Claudio Giannetti, Gabriele Ferrini +6
In this letter we demonstrate the possibility to determine the temporal and spectral structure (spectrogram) of a complex light pulse exploiting the ultrafast switching character o…
Disentangling thermal and non-thermal excited states in a charge-transfer insulator by time-and-frequency resolved pump-probe spectroscopy
Claudio Giannetti, Goran Zgrablic, Cristina Consani +6
Time-and-frequency resolved pump-probe optical spectroscopy is used to investigate the effect of the impulsive injection of delocalized excitations through a charge-transfer proces…
Ultrafast laser pulses to detect and generate fast thermo-mechanical transients in matter
C. Giannetti, F. Banfi, D. Nardi +2
The use of femtosecond laser pulses to impulsively excite thermal and mechanical transients in matter has led, in the last years, to the development of picosecond acoustics. Recent…
Pseudo-surface acoustic waves in hypersonic surface phononic crystals
D. Nardi, F. Banfi, C. Giannetti +3
We present a theoretical framework allowing to properly address the nature of surface-like eigenmodes in a hypersonic surface phononic crystal, a composite structure made of period…
