Flat Band Generation through Interlayer Geometric Frustration in Intercalated Transition Metal Dichalcogenides
Yawen Peng, Ren He, Peng Li +6
Electronic flat bands can lead to rich many-body quantum phases by quenching the electron's kinetic energy and enhancing many-body correlation. The reduced bandwidth can be realize…
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…
Signature of preformed pairs in angle-resolved photoemission spectroscopy
Klemen KovaÄ, Alberto Nocera, Andrea Damascelli +2
We use density matrix renormalization group (DMRG) and variational exact diagonalization (VED) to calculate the single-electron removal spectral weight for the Hubbard-Holstein mod…
Hund flat band in a frustrated spinel oxide
Dongjin Oh, Alexander Hampel, Joshua P. Wakefield +26
Electronic flat bands associated with quenched kinetic energy and heavy electron mass have attracted great interest for promoting strong electronic correlations and emergent phenom…
