Decoupled nematic and magnetic criticality in FeSeS
Jake Ayres, Matija Čulo, Jonathan Buhot +7
Electronic nematicity in correlated metals often occurs alongside another instability such as magnetism. As a result, the question remains whether nematicity alone can drive unconv…
Fermi surface reconstruction and electron dynamics at the charge-density-wave transition in TiSe2
Patrick Knowles, Bo Yang, Takaki Muramatsu +5
The evolution of the charge carrier concentrations and mobilities are examined across the charge-density-wave (CDW) transition in TiSe2. Combined quantum oscillation and magnetotra…
High-Field Quantum Disordered State in -RuCl3: Spin Flips, Bound States, and a Multi-Particle Continuum
A. Sahasrabudhe, D. A. S. Kaib, S. Reschke +15
Layered -RuCl3 has been discussed as a proximate Kitaev spin liquid compound. Raman and THz spectroscopy of magnetic excitations confirm that the low-temperature antiferromagnet…
Coexistence of orbital and quantum critical magnetoresistance in FeSeS
S. Licciardello, N. Maksimovic, J. Ayres +9
The recent discovery of a non-magnetic nematic quantum critical point (QCP) in the iron chalcogenide family FeSeS has raised the prospect of investigating, in isolati…
Anisotropic Kondo pseudo-gap in URu2Si2
J. Buhot, X. Montiel, Y. Gallais +8
A polarized electronic Raman scattering study reveals the emergence of symmetry dependence in the electronic Raman response of single crystalline URuSi below the Kondo…
Raman Active High Energy Excitations in URuSi
Jonathan Buhot, Yann Gallais, Maximilien Cazayous +5
We have performed Raman scattering measurements on URuSi single crystals on a large energy range up to 1300 cm and in all the Raman active symmetries as a fun…
Driving spin excitations by hydrostatic pressure in BiFeO3
J. Buhot, C. Toulouse, Y. Gallais +10
Optical spectroscopy has been combined with computational and theoretical techniques to show how the spin dynamics in the model multiferroic BiFeO3 responds to the application of h…
Optical conductivity of URuSi in the Kondo Liquid and Hidden-Order Phases
R. P. S. M. Lobo, J. Buhot, M. A. Méasson +4
We measured the polarized optical conductivity of URuSi from room temperature down to 5 K, covering the Kondo state, the coherent Kondo liquid regime, and the hidden-order…
Symmetry of the Excitations in the Hidden Order State of URu2Si2
J. Buhot, M. -A. Méasson, Y. Gallais +4
We have performed polarized electronic Raman scattering on URu2Si2 single crystals at low temperature down to 8 K in the hidden order state and under magnetic field up to 10 T. The…
Switching of the magnetic order in CeRhInSn in the vicinity of its quantum critical point
S. Raymond, J. Buhot, E. Ressouche +3
We report neutron diffraction experiments performed in the tetragonal antiferromagnetic heavy fermion system CeRhInSn in its (, ) phase diagram up to the vicini…
Antiferromagnetism and Superconductivity in CeRhIn
Georg Knebel, Jonathan Buhot, Dai Aoki +4
We discuss recent results on the heavy fermion superconductor CeRhIn which presents ideal conditions to study the strong coupling between the suppression of antiferromagnetic o…
