Unveiling the Interplay of Charge and Magnetic Excitations in HgBaCaCuO
Karn Rongrueangkul, Martina Fedele, Leonardo Martinelli +10
Unraveling the mechanism that binds electrons into Cooper pairs in cuprate high-temperature superconductors remains one of the most fundamental challenges in condensed-matter physi…
Revealing the nature of the charge density wave order of ErTe via Raman scattering under anisotropic strain
Theotime Freitas, Mattia Udina, Alexandr Alekhin +7
The nature of the charge density wave (CDW) order of the rare-earth tritelluride ErTe3 is investigated by Raman scattering under anisotropic strain. The CDW state of ErTe3 is uncon…
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…
Raman Response of the Charge Density Wave in Cuprate Superconductors
Moallison F. Cavalcante, S. Bag, I. Paul +3
We study the Raman response, for and light-polarization symmetries, of the charge density wave phase appearing in the underdoped region of cuprate superconductors…
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…
