Observation of large multiple scattering effects in ultrafast electron diffraction on single crystal silicon
I. Gonzalez Vallejo, G. Gallé, B. Arnaud +8
We report on ultrafast electron diffraction on high quality single crystal silicon. The ultrafast dynamics of the Bragg peaks exhibits a giant photo-induced response which can only…
Electron-hole balanced dynamics in the type-II Weyl semimetal candidate WTe2
M. Caputo, L. Khalil, E. Papalazarou +5
We present a time- and angular-resolved photoemission (TR-ARPES) study of the transition- metal dichalcogenide WTe2, a candidate type II Weyl semimetal exhibiting extremely large m…
Revisiting the origin of satellites in core level photoemission of transparent conducting oxides: the case of -doped SnO
F. Borgatti, J. A. Berger, D. Céolin +14
The longstanding problem of interpretation of satellite structures in core level photoemission spectra of metallic systems with a low density of conduction electrons is addressed u…
Many-body perturbation theory and non-perturbative approaches: the screened interaction as key ingredient
Walter Tarantino, Bernardo S. Mendoza, Pina Romaniello +2
Many-body perturbation theory is often formulated in terms of an expansion in the dressed instead of the bare Green's function, and in the screened instead of the bare Coulomb inte…
Raman spectroscopy of femtosecond multi-pulse irradiation of vitreous silica: experiment and simulation
N. S. Shcheblanov, M. E. Povarnitsyn, K. N. Mishchik +1
We report an experimental and numerical study of femtosecond multi-pulse laser-induced densification in vitreous silica (v-SiO2) and its signature in Raman spectra. We compare the…
Using controlled disorder to probe the interplay between charge order and superconductivity in NbSe2
Kyuil Cho, M. Konczykowski, S. Teknowijoyo +10
The interplay between superconductivity and charge density waves (CDW) in -NbSe2 is not fully understood despite decades of study. Artificially introduced disorder can tip the d…
