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…

Roles of band gap and Kane electronic dispersion in the THz-frequency nonlinear optical response in HgCdTe

Davide Soranzio, Elsa Abreu, Sarah Houver +7

Materials with linear electronic dispersion often feature high carrier mobilities and unusually strong nonlinear optical interactions. In this work, we investigate the THz nonlinea…

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.…
