Unveiling the Orbital Texture of 1T-TiTe using Intrinsic Linear Dichroism in Multidimensional Photoemission Spectroscopy
Samuel Beaulieu, Michael Schüler, Jakub Schusser +9
The momentum-dependent orbital character in crystalline solids, referred to as orbital texture, is of capital importance in the emergence of symmetry-broken collective phases such…
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…
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…
Time- and momentum-resolved photoemission studies using time-of-flight momentum microscopy at a free-electron laser
Dmytro Kutnyakhov, Rui Patrick Xian, Maciej Dendzik +38
Time-resolved photoemission with ultrafast pump and probe pulses is an emerging technique with wide application potential. Real-time recording of non-equilibrium electronic process…
