Attosecond metrology of 2D charge distribution in molecules
V. Loriot, A. Boyer, S. Nandi +10
Photoionization as a half-scattering process is not instantaneous. Usually, time delays in photoionization are of the order of few tens of attoseconds (1 as = 10 s). While…
Studying the interaction between VUV photons and PAHs in relevant astrophysical conditions
A Marciniak, A Bonnamy, S Zamith +7
PIRENEA and PIRENEA 2 are experimental setups dedicated to the study of fundamental molecular processes involving species of astrochemical interest. The coupling of a VUV source to…
Transient measurement of phononic states with covariance-based stochastic spectroscopy
G. Sparapassi, S. M. Cavaletto, J. Tollerud +6
We present a novel approach to transient Raman spectroscopy, which combines stochastic probe pulses and a covariance-based detection to measure stimulated Raman signals in alpha-qu…
Photodissociation of aliphatic PAH derivatives under relevant astrophysical conditions
Alexandre Marciniak, Christine Joblin, Giacomo Mulas +2
The interaction of polycyclic aromatic hydrocarbons (PAHs) with vacuum ultraviolet (VUV) photons triggers the emission of the well-known aromatic infrared bands (AIBs) but other me…
Anisotropic Time-Domain Electronic Response in Cuprates
Francesca Giusti, Angela Montanaro, Alexandre Marciniak +9
Superconductivity in the cuprates is characterized by spatial inhomogeneity and an anisotropic electronic gap of d-wave symmetry. The aim of this work is to understand how this ani…
Visible pump -- mid infrared pump -- broadband probe: development and characterization of a three-pulse setup for single-shot ultrafast spectroscopy at 50 kHz
Angela Montanaro, Francesca Giusti, Matija Colja +10
We report here an experimental setup to perform three-pulse pump-probe measurements over a wide wavelength and temperature range. By combining two pump pulses in the visible (650-9…
Time-resolved multimode heterodyne detection for dissecting coherent states of matter
Filippo Glerean, Giacomo Jarc, Alexandre Marciniak +6
Unveiling and controlling the coherent evolution of low energy states is a key to attain light driven new functionalities of materials. Here we investigate the coherent evolution o…
Vibrational coherent control of localized d-d electronic excitation
Alexandre Marciniak, Stefano Marcantoni, Francesca Giusti +10
Addressing the role of quantum coherence in the interplay between the different matter constituents (electrons, phonons and spin) is a critical step towards understanding transitio…
Femtosecond Covariance Spectroscopy
J. Tollerud, G. Sparapassi, A. Montanaro +9
The success of non-linear optics relies largely on pulse-to-pulse consistency. In contrast, covariance based techniques used in photoionization electron spectroscopy and mass spect…
Signatures of enhanced superconducting phase coherence through MID-IR excitation in optimally doped Y-Bi2212
Francesca Giusti, Alexandre Marciniak, Francesco Randi +7
Optimally doped cuprate superconductors are characterized by the presence of superconducting fluctuations in a relatively large temperature region above the critical transition tem…
Mapping the X-Ray Emission Region in a Laser-Plasma Accelerator
S. Corde, C. Thaury, K. Ta Phuoc +13
The x-ray emission in laser-plasma accelerators can be a powerful tool to understand the physics of relativistic laser-plasma interaction. It is shown here that the mapping of beta…
