Zusammenfassung

We performed angle-resolved photoemission spectroscopy (ARPES) of bulk
2H-WSe$_2$ for different crystal orientations linked to each other by
time-reversal symmetry. We introduce a new observable called time-reversal
dichroism, which quantifies the modulation of the photoemission intensity upon
effective time-reversal operation. We demonstrate that the hidden
orbital-texture of the crystal's electronic structure leaves its imprint onto
the time-reversal dichroism, due to multiple orbitals interference effects in
photoemission. Our experimental results are in quantitative agreement with
state-of-the-art fully relativistic calculations performed using the one-step
model of photoemission. While spin-resolved ARPES probes the spin component of
entangled spin-orbital texture in multiorbital systems, we demonstrate that
time-reversal dichroism is sensitive to its orbital-texture counterpart.
