Photoemission tomography of excitons in 2D systems: momentum-space signatures of correlated electron-hole wave functions
Siegfried Kaidisch, Amir Kleiner, Sivan Refaely-Abramson +2
The momentum-space signatures of excitons can be experimentally accessed through time-resolved (pump-probe) photoelectron spectroscopy. In this work, we develop a computational fra…
Magnetic brightening of light-like excitons in a monolayer semiconductor
A. Delhomme, T. Amit, P. Ji +4
Monolayer transition-metal dichalcogenides, such as WSe, are direct gap, multi-valley semiconductors. Long-range electron-hole exchange interactions mix the valleys, yielding d…
Strain-induced exciton mobility in layered WS2 from first principles
Amir Kleiner, Sivan Refaely-Abramson
Exciton mobility in two-dimensional semiconductors is a key ingredient in materials-based design of optoelectronic functionalities. Monolayer transition metal dichalcogenides (TMDs…
Data-Driven Reconstruction and Characterization of Stochastic Dynamics via Dynamical Mode Decomposition
Adva Baratz, Loris Maria Cangemi, Assaf Hamo +2
Noise fundamentally limits the performance and predictive capabilities of classical and quantum dynamical systems by degrading stability and obscuring intrinsic dynamical character…
Exciton-Exciton Annihilation Mediated by Many-Body Coulomb and Phonon Interactions: An Ab Initio Study
Guy Vosco, Sivan Refaely-Abramson
Exciton-exciton annihilation (EEA), in which two excitons interact to generate high-energy excitations, is an important non-radiative channel in light-induced excited-state relaxat…
Generalized many-body exciton g-factors: magnetic hybridization and non-monotonic Rydberg series in monolayer WSe
Paulo E. Faria Junior, Daniel Hernangómez-Pérez, Tomer Amit +2
Magneto-optics of low dimensional semiconductors, such as monolayer transition metal dichalcogenides, offers a vast playground for exploring complex quantum phenomena. However, cur…
