Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
A quantitative comparison of time-of-flight momentum microscopes and hemispherical analyzers for time- and angle-resolved photoemission spectroscopy experiments
J. Maklar, S. Dong, S. Beaulieu +7
Time-of-flight-based momentum microscopy has a growing presence in photoemission studies, as it enables parallel energy- and momentum-resolved acquisition of the full photoelectron…
Bright, polarization-tunable high repetition rate extreme ultraviolet beamline for coincidence electron-ion imaging
Antoine Comby, Etienne Bloch, Sandra Beauvarlet +9
After decades of supremacy of the Titanium:Sapphire technology, Ytterbium-based high-order harmonic sources are emerging as an interesting alternative for experiments requiring hig…
Photoionization of chiral molecules by counter-rotating bicircular laser fields: a chiral attoclock
Samuel Beaulieu, Sylvain Larroque, Antoine Comby +6
Measuring and controlling the ionization dynamics by intense laser fields has recently led to important breakthroughs, from the investigation of tunneling time delays to attosecond…
Revealing Hidden Orbital Pseudospin Texture with Time-Reversal Dichroism in Photoelectron Angular Distributions
Samuel Beaulieu, Jakub Schusser, Shuo Dong +12
We performed angle-resolved photoemission spectroscopy (ARPES) of bulk 2H-WSe for different crystal orientations linked to each other by time-reversal symmetry. We introduce a…
A machine learning route between band mapping and band structure
Rui Patrick Xian, Vincent Stimper, Marios Zacharias +9
Electronic band structure (BS) and crystal structure are the two complementary identifiers of solid state materials. While convenient instruments and reconstruction algorithms have…
Attosecond-resolved photoionization of chiral molecules
Samuel Beaulieu, Antoine Comby, Alex Clergerie +13
Chiral light-matter interactions have been investigated for two centuries, leading to the discovery of many chiroptical processes used for discrimination of enantiomers. Whereas mo…
Observation of an excitonic Mott transition through ultrafast core--conduction photoemission spectroscopy
Maciej Dendzik, R. Patrick Xian, Enrico Perfetto +19
Time-resolved soft-X-ray photoemission spectroscopy is used to simultaneously measure the ultrafast dynamics of core-level spectral functions and excited states upon excitation of…
Ultrafast Dynamical Lifshitz Transition
Samuel Beaulieu, Shuo Dong, Nicolas Tancogne-Dejean +9
Fermi surface is at the heart of our understanding of metals and strongly correlated many-body systems. An abrupt change in the Fermi surface topology, also called Lifshitz transit…
