Research interests

My research centers on the field of experimental solid-state physics, with a specific emphasis on quantum materials exhibiting remarkable properties due to the presence of strongly correlated electrons. I am intrigued by the simultaneous existence or competition of various orders within these systems, encompassing phenomena such as metal-insulator transitions (Mott physics), unconventional superconductivity, frustrated magnetism, and multiferroics.

I am based at the Solid State Physics Laboratory, where I have developed an X-ray diffraction setup under high pressure and low temperature conditions. This setup allows for the measurement of both powders or single crystals. Concurrently, I am an affiliated scientist at the SOLEIL synchrotron, working on the GALAXIES beamline dedicated to X-ray absorption and emission spectroscopy (XAS, XES, and RIXS). I am also affiliated with the Léon Brillouin Laboratory at CEA Saclay, focusing on themes related to neutron diffraction and inelastic neutron scattering.

  • X-ray Scattering (XRD, XAS, XES and RIXS)
  • Neutron Scattering (Diffraction, INS)
  • Infrared and Raman Spectroscopy

Sample Environment

BaM2X3 : quasi 1d strongly correlated materials
(ANR COCOM)

BaM2X3 (M : Fe, Co, Ni, X : S, Se or Te) family, exemplified by BaFe2Se3, are 1d systems presenting mutliple coexisting and competing phases : ferroelectricity, block magnetism, metal-insulator transition, superconductivity and multiferroicity. I am focused on the multi-dimensional phase diagram : doping, substitution, pressure, temperature, magnetic and electric field.

RMn2O5 multiferroics

RMn2O5 (R=Rare Earth) are multiferroic materials presenting a strong magneto-electric coupling. The multiple exchange interactions between Mn-Mn and Mn-R spins generate a large range of instabilities, with commensurate and incommensurate propagation vectors evolving as function of temperature, magnetic field, pressure and composition (R).

I joined the MATRIX group at Laboratoire de Physique des Solides in Orsay. At this occasion, I launched new activities related to the multiferroics materials on RMn2O5, starting to investigate the interplay between order parameters under different conditions. I developped High Pressure X-Ray diffraction setup at the lab, for both powder and single cristal diffraction at high pressure and low temperature. This includes new Diamond Anvil Cell development together with cryostat specifically designed for such cells.
