Reexamining Circular Dichroism in Photoemission From a Topological Insulator
Ittai Sidilkover, Yun Yen, Sunil Wilfred D'Souza +10
The orbital angular momentum (OAM) of electron states is an essential ingredient for topological and quantum geometric quantities in solids. For example, Dirac surface states with…
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…
Surface band characters of Weyl semimetal candidate material MoTe revealed by one-step ARPES theory
Ryota Ono, Alberto Marmodoro, Jakub Schusser +7
The layered 2D-material MoTe in the T crystal phase is a semimetal which has theoretically been predicted to possess topologically non-trivial bands corresponding to Weyl f…
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…
Bulk and surface electronic states in the dosed semimetallic HfTe
Zakariae El Youbi, Sung Won Jung, Saumya Mukherjee +8
The dosing of layered materials with alkali metals has become a commonly used strategy in ARPES experiments. However, precisely what occurs under such conditions, both structurally…
Spin-, time- and angle-resolved photoemission spectroscopy on WTe
Mauro Fanciulli, Jakub Schusser, Min-I Lee +12
We combined a spin-resolved photoemission spectrometer with a high-harmonic generation (HHG) laser source in order to perform spin-, time- and angle-resolved photoemission spectros…
