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…

Tracking the local order parameter through the Hubbard exciton decoherence time in the Mott-Hubbard insulator LaVO3
Alessandra Milloch, Paolo Franceschini, Pablo Villar-Arribi +9
The prototypical Mott-Hubbard insulator LaVO3 undergoes a structural phase transition accompanied by the onset of spin and orbital ordering below 140 K. By combining ultrafast opti…

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…
