Control of the MoTe Fermi Surface by Nb Doping
Andrew P. Weber, Iñigo Robredo, Philipp Rüssmann +8
Ab initio calculations and angle-resolved photoemission experiments show that the bulk and surface electronic structure of Weyl semimetal candidate MoTe changes significantly b…
Impact of a Fano resonance on the measured transition time scale in solid state photoemission
Fei Guo, Dmitry Usanov, Eduardo B. Guedes +3
Fundamental quantum transition time scales are accessible through the spin polarization of photoelectrons coming from initially spin-degenerate states for solid-state materials . I…
Extraction of the self energy and Eliashberg function from angle resolved photoemission spectroscopy using the xARPES code
Thomas P. van Waas, Christophe Berthod, Jan Berges +3
Angle-resolved photoemission spectroscopy is a powerful experimental technique for studying anisotropic many-body interactions through the electron spectral function. Existing atte…
Duality and degeneracy lifting in two-dimensional electron liquids on SrTiO(001)
Igor Sokolović, Eduardo B. Guedes, Thomas P. van Waas +7
Two-dimensional electron liquids (2DELs) have increasing technological relevance for ultrafast electronics and spintronics, yet significant gaps in their fundamental understanding…
Real and Reciprocal Space Characterization of the 3-Dimensional Charge Density Wave in Quasi-1-Dimensional CuTe
Fei Guo, Michele Puppin, Lukas Hellbruck +4
Low-dimensional materials are susceptible to electronic instabilities such as charge density waves (CDWs), originating from a divergence in the Lindhard electron response function,…
High-resolution MHz time- and angle-resolved photoemission spectroscopy based on a tunable vacuum ultraviolet source
Lukas Hellbrück, Michele Puppin, Fei Guo +7
Time and angle-resolved photoemission spectroscopy (trARPES) allows direct mapping of the electronic band structure and its dynamic response on femtosecond timescales. Here, we pre…
