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…
Application of the exact-factorization density-functional perturbation approach to pentacene crystal and monolayer MoS2
Rachel Steinitz-Eliyahu, Galit Cohen, Guy Vosco +3
Non-adiabatic effects arising from electron-phonon interactions are often neglected within the Born-Oppenheimer (BO) approximation, which assumes that electronic states adjust inst…
Zero-phonon line emission of single photon emitters in helium-ion treated MoS
Katja Barthelmi, Tomer Amit, Mirco Troue +13
We explore the zero-phonon line of single photon emitters in helium-ion treated monolayer MoS, which are currently understood in terms of single sulfur-site vacancies. By compa…
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…
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…
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…
