Emergent ultrafast phenomena in correlated oxides and heterostructures
M. Gandolfi, L. Celardo, F. Borgonovi +4
The possibility of investigating the dynamics of solids on timescales faster than the thermalization of the internal degrees of freedom has disclosed novel non-equilibrium phenomen…
Thermo-mechanical behavior of surface acoustic waves in ordered arrays of nanodisks studied by near infrared pump-probe diffraction experiments
C. Giannetti, B. Revaz, F. Banfi +10
The ultrafast thermal and mechanical dynamics of a two-dimensional lattice of metallic nano-disks has been studied by near infrared pump-probe diffraction measurements, over a temp…
Snapshots of the retarded interaction of charge carriers with ultrafast fluctuations in cuprates
S. Dal Conte, L. Vidmar, D. Golež +18
One of the pivotal questions in the physics of high-temperature superconductors is whether the low-energy dynamics of the charge carriers is mediated by bosons with a characteristi…
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…
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…
