Electron irradiation reveals robust fully gapped superconductivity in LaNiGa
S. Ghimire, K. R. Joshi, E. H. Krenkel +8
The effects of 2.5 MeV electron irradiation were studied in the superconducting phase of single crystals of LaNiGa, using measurements of electrical transport and radio-frequen…
Anisotropic multiband superconductivity in 2M-WS probed by controlled disorder
Sunil Ghimire, Kamal R. Joshi, Marcin Konczykowski +10
The intrinsically superconducting Dirac semimetal 2M-WS is a promising candidate to realize proximity-induced topological superconductivity in its protected surface states. A…
Bulk evidence of anisotropic -wave pairing with no sign change in the kagome superconductor CsVSb
M. Roppongi, K. Ishihara, Y. Tanaka +12
The recently discovered kagome superconductors VSb ( = K, Rb, Cs) possess a unique band structure with van Hove singularities and Dirac dispersions, in which unusual…
Possible unconventional pairing in superconductors revealed by controlling disorder
E. H. Krenkel, M. A. Tanatar, M. Konczykowski +11
We study the evolution of temperature-dependent resistivity with controlled point-like disorder induced by 2.5 MeV electron irradiation in stoichiometric compositions of the "3-4-1…
Terahertz pulse-driven collective mode in the nematic superconducting state of BaKFeAs
Romain Grasset, Kota Katsumi, Pierre Massat +4
We investigate the iron-based superconductor BaKFeAs using intense terahertz (THz) light. In the superconducting state a THz Kerr signal is observed and assigne…
Exploration of the Hg-based cuprate superconductors by Raman spectroscopy under hydrostatic pressure
N. Auvray, B. Loret, S. Chibani +8
The superconducting phase of the (Hg-1201) and (Hg-1223) cuprates has been investiga…
Pressure induced collapse of the charge density wave and Higgs mode visibility in 2H-TaS
Romain Grasset, Yann Gallais, Alain Sacuto +4
The pressure evolution of the Raman active electronic excitations of the transition metal dichalcogenides 2H-TaS is followed through the pressure phase diagram embedding incomm…
Collapse of critical nematic fluctuations in FeSe under pressure
Pierre Massat, Yundi Quan, Romain Grasset +8
We report the evolution of the electronic nematic susceptibility in FeSe via Raman scattering as a function of hydrostatic pressure up to 5.8 GPa where the superconducting transiti…
Higgs-mode radiance and charge-density-wave order in 2H-NbSe
Romain Grasset, Tommaso Cea, Yann Gallais +5
Despite being usually considered two competing phenomena, charge-density-wave and superconductivity coexist in few systems, the most emblematic one being the transition metal dicha…
