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…
Contrasting Spin Excitations in Octahedral and Square-Planar n=8 Ruddlesden-Popper Nickelates
K. Scott, H. LaBollita, G. A. Pan +15
The discovery of superconductivity in reduced square-planar nickelates marked a major advance in identifying structural and electronic analogs to the high- cuprates. The more…
Selective electron-phonon coupling strength from nonequilibrium optical spectroscopy: The case of MgB
S. Mor, F. Boschini, E. Razzoli +9
The coupling between quasiparticles and bosonic excitations rules the energy transfer pathways in condensed matter systems. The possibility of inferring the strength of specific co…
Direct measurement of coherent nodal and antinodal dynamics in underdoped Bi-2212
Rishabh Mishra, Jonathan O. Tollerud, Paolo Franceschini +8
The physics of strongly correlated materials is deeply rooted in electron interactions and their coupling to low-energy excitations. Unraveling the competing and cooperative nature…
Dynamic charge order from strong correlations in the cuprates
Eduardo H. da Silva Neto, Alex Frano, Fabio Boschini
Charge order has been a central focus in the study of cuprate high-temperature superconductors due to its intriguing yet not fully understood connection to superconductivity. Recen…
