Enhanced sliding in the coexisting Charge Density Wave phase of strained TbTe3
Antoine Gallo Frantz, Aleksander Sinchenko, Luc Ortega +5
In the last years, the application of mechanical tensile stress has been shown to trigger unconventional phases in quantum materials. Recently, an orientational transition of the c…
Tuning Charge Density Wave transitions through lattice strain in NbSe3
Antoine Gallo Frantz, Aleksander Sinchenko, Luc Ortega +7
The Charge Density Wave (CDW) state is a perfect example of a combined structural and electronic state, both characterized by a periodic lattice distortion and an electronic modula…
Charge Density Wave bending observed by Xfel source acting as a tunable electronic lens for hard x-rays
E. Bellec, D. Ghoneim, A. Gallo +6
Ultrafast X-ray diffraction by the LCLS free-electron laser has been used to probe Charge Density Wave (CDW) systems under applied external currents. At sufficiently low currents,…
Tracking defects of Electronic Crystals by Coherent X-ray Diffraction
David Le Bolloc'h, E. Bellec, N. Kirova +1
In this article, we review different studies based on advanced x-ray diffraction techniques - especially coherent x-ray diffraction - that allowed us to reveal the behaviour of suc…
Charge-Density-Waves Tuned by Crystal Symmetry
A. Gallo-Frantz, A. A. Sinchenko, D. Ghoneim +10
The electronic orders appearing in condensed matter systems are originating from the precise arrangement of atoms constituting the crystal as well as their nature. This teneous rel…
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…
Laser-Induced Charge-Density-Wave Transient Depinning in Chromium
V. Jacques, C. Laulhé, N. Moisan +2
We report here on time-resolved x-ray diffraction measurements following femtosecond laser excitation in pure bulk chromium. Comparing the evolution of incommensurate charge-densit…
Ultrafast evolution and transient phases of the prototype out-of-equilibrium Mott-Hubbard material V2O3
G. Lantz, B Mansart, D. Grieger +17
The study of photoexcited strongly correlated materials is attracting growing interest since their rich phase diagram often translates into an equally rich out-of-equilibrium behav…
Collective transport of charges in charge density wave systems based on traveling soliton lattices
A. Rojo-Bravo, V. L. R. Jacques, David Le Bolloc'h
Solitons are peculiar excitations that appear in a wide range of nonlinear systems such as in fluids or optics. We show here that the collective transport of charges observed in ch…
Effect of dimensionality on sliding charge density waves. The case of the quasi-two dimensional TbTe system probed by coherent x-ray diffraction

V. L. R. Jacques, E. Pinsolle, S. Ravy +2
Spatial uctuations of spin density wave (SDW) and charge density wave (CDW) in chromium have been compared by combining coherent and simultaneous X-ray diffraction experiments. Des…
X-ray Coherent diffraction interpreted through the fractional Fourier transform
David Le Bolloc'h, Jean-Francois Sadoc
Diffraction of coherent x-ray beams is treated through the Fractionnal Fourier transform. The transformation allow us to deal with coherent diffraction experiments from the Fresnel…
