Ultrafast dynamics of bright and dark excitons in monolayer WSe and heterobilayer WSe/MoS
Jan Philipp Bange, Paul Werner, David Schmitt +15
The energy landscape of optical excitations in mono- and few-layer transition metal dichalcogenides (TMDs) is dominated by optically bright and dark excitons. These excitons can be…
Coherent two-dimensional multiphoton photoelectron spectroscopy of metal surfaces
Marcel Reutzel, Andi Li, Hrvoje Petek
Light interacting with metals elicits an ultrafast coherent many-body screening response on sub- to few-femtosecond time-scales, which makes its experimental observation challengin…
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…
Direct visualization of hybrid excitons in van der Waals heterostructures
Giuseppe Meneghini, Marcel Reutzel, Stefan Mathias +2
Van der Waals heterostructures show fascinating physics including trapped moire exciton states, anomalous moire exciton transport, generalized Wigner crystals, etc. Bilayers of tra…
Unraveling Femtosecond Spin and Charge Dynamics with EUV T-MOKE Spectroscopy
Henrike Probst, Christina Möller, Maren Schumacher +7
The magneto-optical Kerr effect (MOKE) in the extreme ultraviolet (EUV) regime has helped to elucidate some of the key processes that lead to the manipulation of magnetism on ultra…
Electromagnetic dressing of the electron energy spectrum of Au(111) at high momenta
Marius Keunecke, Marcel Reutzel, David Schmitt +10
Light-engineering of quantum materials via electromagnetic dressing is considered an on-demand approach for tailoring electronic band dispersions and even inducing topological phas…
