Photo-induced carrier dynamics in InSb probed with broadband THz spectroscopy based on BNA crystals
Elodie Iglesis, Alexandr Alekhin, Maximilien Cazayous +3
We report an optical pump - terahertz (THz) probe study of the photoinduced transient carrier dynamics in the low bandgap semiconductor Indium Antimonide (InSb). Using an organic N…
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…
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.…
Non-collinear and strongly asymmetric polar moments at back-gated SrTiO3 interfaces
Fryderyk Lyzwa, Yurii G. Pashkevich, Premysl Marsik +15
The highly mobile electrons at the interface of SrTiO3 with other oxide insulators, such as LaAlO3 or AlOx, are of great current interest. A vertical gate voltage allows controllin…
