Dielectric Screening in Electromagnetic Dressing of Semiconductors

Quentin Courtade, Umberto Dellasette, Sotirios Fragkos +4

Nonequilibrium manipulation of quantum materials via electromagnetic dressing provides an on-demand route to tailoring electronic band structures through Floquet engineering. Time-…

Time- and Polarization-Resolved Extreme Ultraviolet Momentum Microscopy

Sotirios Fragkos, Quentin Courtade, Olena Tkach +7

We report the development of an instrument combining an ultrafast, high-repetition-rate, polarization-tunable monochromatic extreme ultraviolet (XUV, 21.6 eV) beamline and a next-g…

Berry Curvature Signatures in Chiroptical Excitonic Transitions

Samuel Beaulieu, Shuo Dong, Viktor Christiansson +10

The topology of the electronic band structure of solids can be described by its Berry curvature distribution across the Brillouin zone. We theoretically introduce and experimentall…

Coherent Light Control of a Metastable Hidden Phase

J. Maklar, S. Dong, J. Sarkar +13

Metastable phases present a promising route to expand the functionality of complex materials. Of particular interest are light-induced metastable phases that are inaccessible under…

Orbital-resolved Observation of Singlet Fission

Alexander Neef, Samuel Beaulieu, Sebastian Hammer +8

Singlet fission may boost photovoltaic efficiency [by transforming a singlet exciton into two triplet excitons and thereby doubling the number of excited charge carriers. The prima…

Polarization-Modulated Angle-Resolved Photoemission Spectroscopy: Towards Circular Dichroism without Circular Photons and Bloch Wavefunction Reconstruction

Michael Schüler, Tommaso Pincelli, Shuo Dong +5

Angle-resolved photoemission spectroscopy (ARPES) is the most powerful technique to investigate the electronic band structure of crystalline solids. To completely characterize the…
