ARPES signatures of trions in van der Waals materials
Giuseppe Meneghini, Maja Löwe, Raul Perea-Causin +5
Angle-resolved photoemission spectroscopy (ARPES) has recently emerged as a direct probe of excitonic correlations in two-dimensional semiconductors, resolving their dispersion and…
The role of non-equilibrium populations in dark exciton formation
Paul Werner, Wiebke Bennecke, Jan Philipp Bange +15
In two-dimensional transition metal dichalcogenide structures, the optical excitation of a bright exciton may be followed by the formation of a plethora of lower energy dark states…
Table-top three-dimensional photoemission orbital tomography with a femtosecond extreme ultraviolet light source
Wiebke Bennecke, Thi Lan Dinh, Jan Philipp Bange +11
Following electronic processes in molecules and materials at the level of the quantum mechanical electron wavefunction with angstrom-level spatial resolution and with full access t…
Algorithmic approaches to avoiding bad local minima in nonconvex inconsistent feasibility
Thi Lan Dinh, Wiebke Bennecke, G. S. Matthijs Jansen +2
We report on the use of algorithms to avoid or move away from ``bad'' local minima in nonconvex optimization. Our study is phenomenological and empirical, focusing on the performan…
