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…
Ultrafast Two-Dimensional Spectroscopy Uncovers Ubiquitous Electron-Paramagnon Coupling in Cuprate Superconductors
Francesco Proietto, Alessandra Milloch, Paolo Franceschini +20
The coupling between electronic excitations and collective bosonic modes is fundamental to the emergence of high-temperature superconductivity in cuprates. Despite extensive effort…
Electron-phonon coupling revealed by charge density fluctuations in cuprate superconductors
Martina Fedele, Giacomo Merzoni, Marco Moretti Sala +6
Electron-phonon coupling (EPC) governs lattice dynamics, charge transport, and collective electronic phases in quantum materials. In several families of unconventional superconduct…
Spin and orbital excitations in undoped infinite layers: a comparison between superconducting PrNiO2 and insulating CaCuO2
Francesco Rosa, Hoshang Sahib, Giacomo Merzoni +9
Infinite-layer nickelates are among the most promising cuprate-akin superconductors, although relevant differences from copper oxides have been reported. Here, we present momentum-…
Formation of Incommensurate Charge Density Waves in Cuprates
H. Miao, R. Fumagalli, M. Rossi +8
Although charge density waves (CDWs) are omnipresent in cuprate high-temperature superconductors, they occur at significantly different wavevectors, confounding efforts to understa…
Re-entrant charge order in overdoped (Bi,Pb)SrCuO outside the pseudogap regime
Y. Y. Peng, R. Fumagalli, Y. Ding +15
Charge modulations are considered as a leading competitor of high-temperature superconductivity in the underdoped cuprates, and their relationship to Fermi surface reconstructions…
Connection between charge-density-wave order and charge transport in the cuprate superconductors
W. Tabis, Y. Li, M. Le Tacon +17
Charge-density-wave (CDW) correlations within the quintessential CuO planes have been argued to either cause [1] or compete with [2] the superconductivity in the cuprates, and…
High-energy spin and charge excitations in electron-doped copper oxide superconductors
K. Ishii, M. Fujita, T. Sasaki +15
The evolution of electronic (spin and charge) excitations upon carrier doping is an extremely important issue in superconducting layered cuprates and the knowledge of its asymmetry…
