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…
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…
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…
Non-trivial topological valence bands of common diamond and zinc-blende semiconductors
Tomáš Rauch, Victor A. Rogalev, Maximilian Bauernfeind +11
The diamond and zinc-blende semiconductors are well-known and have been widely studied for decades. Yet, their electronic structure still surprises with unexpected topological prop…
A setup for extreme-ultraviolet ultrafast angle-resolved photoelectron spectroscopy at 50-kHz repetition rate
Jan Heye Buss, He Wang, Yiming Xu +11
Time- and angle-resolved photoelectron spectroscopy (trARPES) is a powerful method to track the ultrafast dynamics of quasiparticles and electronic bands in energy and momentum spa…
Correlation-driven charge order in a frustrated two-dimensional atom lattice
Florian Adler, Stephan Rachel, Manuel Laubach +4
We thoroughly examine the ground state of the triangular lattice of Pb on Si(111) using scanning tunneling microscopy. We detect charge-order, accompanied by a subtle structural re…
