Disentangling lattice and electronic instabilities in the excitonic insulator candidate TaNiSe by nonequilibrium spectroscopy
Kota Katsumi, Alexandr Alekhin, Sofia-Michaela Souliou +7
TaNiSe is an excitonic insulator candidate showing the semiconductor/semimetal-to-insulator (SI) transition below = 326 K. However, since a structural transi…
Spin singlet and quasiparticles excitations in cuprate superconductors
M. Mezidi, A. Alekhin, G. D. Gu +5
We followed step by step the transition from an antiferromagnetic (AF) Mott insulator to a superconducting (SC) metal in the BiSrCaCuO (Bi-2212) cuprate using…
Nematic fluctuations mediated superconductivity revealed by anisotropic strain in Ba(FeCo)As
J. -C. Philippe, A. Lespinas, J. Faria +7
Anisotropic strain is an external field capable of selectively addressing the role of nematic fluctuations in promoting superconductivity. We demonstrate this using polarization-re…
Thermally populated versus field-induced triplon bound states in the Shastry-Sutherland lattice SrCu(BO)
Dirk Wulferding, Youngsu Choi, Seungyeol Lee +6
The Shastry-Sutherland compound SrCu(BO) constituting orthogonally coupled dimers harbors a singlet ground state. The confluence of strong interdimer interaction…
Elastic and magnetoelastic properties of TbMnO3 single crystal by nanosecond time resolved acoustics and first-principles calculations
Pierre Hemme, Philippe Djemia, Pauline Rovillain +8
Time resolved pump and probe acoustics and first-principles calculations were employed to assess elastic properties of the TbMnO3 perovskite manganite having orthorhombic symmetry.…
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…
