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…
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…
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…
Tricritical Point and the Doping Dependence of the Order of the Ferromagnetic Phase Transition of La1-xCaxMnO3
D. Kim, B. Revaz, B. L. Zink +3
We report the doping dependence of the order of the ferromagnetic metal to paramagnetic insulator phase transition in La1-xCaxMnO3. At x = 0.33, magnetization and specific heat dat…
Specific heat of MgB_2 after irradiation
Yuxing Wang, Frederic Bouquet, Ilya Sheikin +6
We studied the effect of disorder on the superconducting properties of polycrystalline MgB_2 by specific-heat measurements. In the pristine state, these measurements give a bulk co…
Observation of an unconventional metal-insulator transition in overdoped CuO_2 compounds
F. Venturini, M. Opel, T. P. Devereaux +7
The electron dynamics in the normal state of BiSrCaCuO is studied by inelastic light scattering over a wide range of doping. A strong anisotropy of the electron…
