Observation of Fermi-Arc Spin Texture in TaAs

Joël Mesot, Jan Hugo Dil, Stefan Peter Muff

We have investigated the spin texture of surface Fermi arcs in the recently discovered Weyl semimetal TaAs using spin- and angle-resolved photoemission spectroscopy. The experimental results demonstrate that the Fermi arcs are spin polarized. The measured ...

Atomic scale electronic structure and response in attosecond photoemission delays: A case study using non-centrosymmetric BiTeCI

Jan Hugo Dil

Attosecond time-resolved photoemission from the differently terminated BiTeCl surfaces yield a photoelectron streaking that cannot be explained by bulk propagation effects alone. Instead, the atomic scale electronic structure and dynamical screening for bo ...

Spin polarization in photoemission from the cuprate superconductor Bi2Sr2CaCu2O8+delta

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli, Andrew Patton Weber

Photoelectrons produced from the excitation of spin-degenerate states in solids can have a sizable spin polarization, which is related to the phase of interfering channels in the photoemission matrix elements. Such spin polarization can be measured by spin ...

Interplay between disorder and electronic correlations in compositionally complex alloys

László Forró, Jan Hugo Dil, Edoardo Martino, Luka Ciric, Xavier François Mettan, Davor Tolj, Trpimir Ivsic

Owing to their exceptional mechanical, electronic, and phononic transport properties, compositionally complex alloys, including high-entropy alloys, represent an important class of materials. However, the interplay between chemical disorder and electronic ...

Entanglement and manipulation of the magnetic and spin-orbit order in multiferroic Rashba semiconductors

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli, Andrew Patton Weber

Entanglement of the spin-orbit and magnetic order in multiferroic materials bears a strong potential for engineering novel electronic and spintronic devices. Here, we explore the electron and spin structure of ferroelectric alpha-GeTe thin films doped with ...

Spin Polarization and Attosecond Time Delay in Photoemission from Spin Degenerate States of Solids

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli

After photon absorption, electrons from a dispersive band of a solid require a finite time in the photoemission process before being photoemitted as free particles, in line with recent attosecond-resolved photoemission experiments. According to the Eisenbu ...

Response of the topological surface state to surface disorder in TlBiSe2

Jan Hugo Dil, Stefan Peter Muff

Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile Tl atoms at room temperature. No ...

High-resolution MHz time- and angle-resolved photoemission spectroscopy based on a tunable vacuum ultraviolet source

Henrik Moodysson Rønnow, Marco Grioni, Fabrizio Carbone, Jan Hugo Dil, Thomas La Grange, Michele Puppin, Fei Guo, Siham Benhabib, Lukas Jürgen Hellbrück

The time- and angle-resolved photoemission spectroscopy (trARPES) allows for direct mapping of the electronic band structure and its dynamic response on femtosecond timescales. Here, we present a new ARPES system, powered by a new fiber-based femtosecond l ...
