Profiling THz Beams With Off-Label Use of Infrared Microbolometric Cameras
Gabriel Nagamine, Carlo Vicario, Tariq Leinen +6
Visualizing the spatial profile of light beams is essential for evaluating irradiance, characterizing beam quality, and achieving precise alignment. In the optical spectral range,…
Melting of magnetic order in by fs laser pulses
Flavio Giorgianni, Max Burian, Namrata Gurung +19
NaOsO has recently attracted significant attention for the strong coupling between its electronic band structure and magnetic ordering. Here, we used time-resolved magnetic X-r…
Terahertz displacive excitation of a coherent Raman-active phonon in VO
Flavio Giorgianni, Mattia Udina, Tommaso Cea +7
Nonlinear processes involving frequency-mixing of light fields set the basis for ultrafast coherent spectroscopy of collective modes in solids. In certain semimetals and semiconduc…
Ultrafast Frustration-Breaking and Magnetophononic Driving of Singlet Excitations in a Quantum Magnet
Flavio Giorgianni, Björn Wehinger, Stephan Allenspach +6
Ideal magnetic frustration forms the basis for the emergence of exotic quantum spin states that are entirely nonmagnetic. Such singlet spin states are the defining feature of the S…
Universal coupling between the photonics and phononics in a 3D graphene sponge
M. Shalaby, C. Vicario, F. Giorgianni +6
Photon-phonon coupling holds strong potential for sound and temperature control with light, opening new horizons in detector technology, remote sound generation and signal broadcas…
High Efficiency and Low Distortion Photoacoustic Effect in 3D Graphene Sponge
Flavio Giorgianni, Carlo Vicario, Mostafa Shalaby +7
The conversion of light in sound plays a crucial role in spectroscopy, applied physics, and technology. In this paper, light sound conversion in 3D graphene sponge through a photot…
Strong nonlinear terahertz response induced by Dirac surface states in Bi2Se3 Topological Insulator
Flavio Giorgianni, Enrica Chiadroni, Andrea Rovere +17
Electrons with a linear energy/momentum dispersion are called massless Dirac electrons and represent the low-energy excitations in exotic materials like Graphene and Topological In…
Subcycle insulator-to-metal transition in vanadium dioxide by terahertz-field-driven tunneling
Flavio Giorgianni, Carlo Vicario, Mostafa Shalaby +4
In vanadium dioxide, the interplay between coherent lattice transformation and electronic correlation drives an insulator-to-metal transition (IMT). This phase commutation can be t…
Optical conductivity of V4O7 across its metal-insulator transition
I. Lo Vecchio, M. Autore, F. D'Apuzzo +6
The optical properties of a V4O7 single crystal have been investigated from the high temperature metallic phase down to the low temperature antiferromagnetic insulating one. The te…
IRIDE White Book, An Interdisciplinary Research Infrastructure based on Dual Electron linacs&lasers
D. Alesini, M. Alessandroni, M. P. Anania +211
This report describes the scientific aims and potentials as well as the preliminary technical design of IRIDE, an innovative tool for multi-disciplinary investigations in a wide fi…
Observation of Dirac plasmons in a topological insulator
P. Di Pietro, M. Ortolani, O. Limaj +9
Plasmons are the quantized collective oscillations of electrons in metals and doped semiconductors. The plasmons of ordinary, massive electrons are since a long time basic ingredie…
