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…
Suppression of Spectral Gap and Flat Bands on a Cuprate Superconductor Side-Surface
Gabriele Domaine, Mihir Date, Sydney K. Y. Dufresne +27
Side surfaces of cuprate superconductors are expected to display a suppressed -wave order parameter and zero-energy topological flat bands with a large density of states, making…
A simulation-based training framework for machine-learning applications in ARPES
MengXing Na, Chris Zhou, Sydney K. Y. Dufresne +2
In recent years, angle-resolved photoemission spectroscopy (ARPES) has advanced significantly in its ability to probe more observables and simultaneously generate multi-dimensional…
Quenching of excitons at grain boundaries in C60 thin films
Rysa Greenwood, Bradley G. Guislain, MengXing Na +12
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and there…
Enhanced coherence and layer-selective charge order in a trilayer cuprate superconductor
S. Smit, M. Bluschke, P. Moen +25
Trilayer cuprates hold the record for the highest superconducting critical temperatures (), yet the underlying mechanism remains elusive. Using time- and angle-resolv…
Tunable Octdong and Spindle-Torus Fermi Surfaces in Kramers Nodal Line Metals
Gabriele Domaine, Moritz H. Hirschmann, Kirill Parshukov +9
It has recently been proposed that all achiral non-centrosymmetric crystals host so-called Kramers nodal lines, which are doubly degenerate band crossings connecting time-reversal…
