A compact approach to higher-resolution resonant inelastic x-ray scattering detection using photoelectrons
Henrik Moodysson Rønnow, Markus Scholz
The detection of inelastically scattered soft x-rays with high energy resolution usually requires large grating spectrometers. Recently, photoelectron spectrometry for analysis of x-rays (PAX) has been rediscovered for modern spectroscopy experiments at sy ...
Iop Publishing Ltd2024Dual-shot approach for polarization retrieval through a scattering medium
A dual-shot technique based on the field basis addition of two statistically independent speckle patterns is developed to recover an input polarization through a scattering layer. It is proposed theoretically, and demonstrated both numerically and experime ...
Iop Publishing Ltd2024Electronic structure and lattice dynamics of 1T-VSe2:Origin of the three-dimensional charge density wave
To characterize in detail the charge density wave (CDW) transition of 1T-VSe2, its electronic structure and lattice dynamics are comprehensively studied by means of x-ray diffraction, muon spectroscopy, angle resolved photoemission (ARPES), diffuse and ine ...
Amer Physical Soc2024Spatial statistics of superposition of two uncorrelated speckle patterns with polarization diversity
A detailed theoretical and experimental study on the effect of the superposition of uncorrelated speckle patterns with polarization diversity on the spatial statistics of the superposed speckle pattern is presented. It is shown that depending on the mutual ...

Trigonal tellurium, a small-gap semiconductor with pronounced magneto-electric and magneto-optical responses, is among the simplest realizations of a chiral crystal. We have studied by spin- and angle-resolved photoelectron spectroscopy its unconventional ...
AMER PHYSICAL SOC2020Tailored-Potential Semiconductor Quantum Nanostructures Grown in Inverted Pyramids
We have focused on the ability to tune the aluminum (Al) content of the AlGaAs alloy along the growth direction in inverted pyramids (by MOVPE), thus tailoring the potential along a QWR nanostructure. Three parabolic-potential QDs (PQDs) of different poten ...
EPFL2019Spin polarization and attosecond time delay in photoemission from solids
In the photoemission process electrons are emitted from a solid upon excitation with UV light. From the measurement of their energy and momentum, angle-resolved photoemission spectroscopy (ARPES) allows to reconstruct the electronic properties of the solid ...
EPFL2018Determination of the time scale of photoemission from the measurement of spin polarization
The Eisenbud-Wigner-Smith (EWS) time delay of photoemission depends on the phase term of the matrix element describing the transition. Because of an interference process between partial channels, the photoelectrons acquire a spin polarization which is also ...
2018Spin 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 ...

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 ...
