Isolating Exciton Dissociation Pathways in ReSe
Bradley G. Guislain, Rysa Greenwood, Matteo Michiardi +13
Strongly bound excitons dominate the optical response in many van der Waals semiconductors, yet distinguishing between the different microscopic processes governing exciton dissoci…
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…
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…
Optically Probing Unconventional Superconductivity in Atomically Thin BiSrCaYCuO
Yunhuan Xiao, Jingda Wu, Jerry I Dadap +11
Atomically thin cuprates exhibiting a superconducting phase transition temperature similar to bulk have recently been realized, although the device fabrication remains a challenge…
Dynamics of non-thermal states in optimally-doped revealed by mid-infrared three-pulse spectroscopy
Angela Montanaro, Enrico Maria Rigoni, Francesca Giusti +13
In the cuprates, the opening of a d-wave superconducting (SC) gap is accompanied by a redistribution of spectral weight at energies two orders of magnitude larger than this gap. Th…
Direct observation of the Higgs particle in a superconductor by non-equilibrium Raman scattering
Tomke E. Glier, Sida Tian, Mika Rerrer +12
Even before its role in electroweak symmetry breaking, the Anderson-Higgs mechanism was introduced to explain the Meissner effect in superconductors. Spontaneous symmetry-breaking…
A spectral function tour of electron-phonon coupling outside the Migdal limit
C. N. Veenstra, G. L. Goodvin, M. Berciu +1
We simulate spectral functions for electron-phonon coupling in a filled band system - far from the asymptotic limit often assumed where the phonon energy is very small compared to…
Evidence of a photoinduced non-thermal superconducting-to-normal-state phase transition in overdoped BiSrCaYCuO
G. Coslovich, C. Giannetti, F. Cilento +9
Here we report extensive ultrafast time-resolved reflectivity experiments on overdoped BiSrCaYCuO single crystals (T=78 K) aimed to clarif…
Electronic structure of MgB from angle-resolved photoemission spectroscopy
H. Uchiyama, K. M. Shen, S. Lee +5
The first angle-resolved photoemission spectroscopy results from MgB single crystals are reported. Close to the K and M directions, three distinct dispersions are observe…
Signature of Superfluid Density in the Single-Particle Excitation Spectrum of Bi2Sr2CaCu2O8+delta
D. L. Feng, D. H. Lu, K. M. Shen +12
We report that the doping and temperature dependence of photoemission spectra near the Brillouin zone boundary of Bi2Sr2CaCu2O8+delta exhibit unexpected sensitivity to the superflu…
Low temperature ellipsometry of NaV2O5
C. Presura, D. van der Marel, A. Damascelli +1
The dielectric function of alpha'NaV2O5 was measured with electric field along the a and b axes in the photon energy range 0.8-4.5 eV for temperatures down to 4K. We observe a pron…
