Nonlinear optical diode effect in a magnetic Weyl semimetal
Philip Johannes Walter Moll, Chunyu Guo, Hao Yang
Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Optical diode effects arising from the Weyl fermions have been theoretically co ...
Nature Portfolio2024Lightning Nowcasting Using Solely Lightning Data
Marcos Rubinstein, Amirhossein Mostajabi
Lightning is directly or indirectly responsible for significant human casualties and property damage worldwide. A timely prediction of its occurrence can enable authorities and the public to take necessary precautionary actions resulting in diminishing the ...
Basel2023DESI mock challenge Halo and galaxy catalogues with the bias assignment method
Cheng Zhao, Ginevra Favole, Yu Yu
Context. We present a novel approach to the construction of mock galaxy catalogues for large-scale structure analysis based on the distribution of dark matter halos obtained with effective bias models at the field level. Aims. We aim to produce mock galaxy ...
EDP SCIENCES S A2023ACACIA: a new method to produce on-the-fly merger trees in the RAMSES code
The implementation of ACACIA, a new algorithm to generate dark matter halo merger trees with the Adaptive Mesh Refinement code RAMSES, is presented. The algorithm is fully parallel and based on the Message Passing Interface. As opposed to most available me ...
OXFORD UNIV PRESS2022The thermally activated deformation behaviour of single-crystalline microcast aluminium wires
Andreas Mortensen, Léa Deillon, Suzanne Godelieve Alphonsine Verheyden
A microcasting process is used to produce high aspect ratio ( > 30) monocrystalline pure aluminium wires with a diameter between 14 and 115 mu m. The role of thermal activation in the plastic deformation of these microwires is measured by means of (single) ...
PERGAMON-ELSEVIER SCIENCE LTD2022Réutilisation des constructions en béton
Ce projet se rapporte au cas d’étude du site du « Strandboden » à Bienne et plus particulièrement au « Pont de Neptune » qui permet la traversée du port de Neptune. Le « Pont de Neptune » est un pont arc en béton armé construit entre 1928 et 1929 qui perme ...
2021Tightening weak lensing constraints on the ellipticity of galaxy-scale dark matter haloes
Cosmological simulations predict that galaxies are embedded into triaxial dark matter haloes, which appear approximately elliptical in projection. Weak gravitational lensing allows us to constrain these halo shapes and thereby test the nature of dark matte ...
EDP SCIENCES S A2021On the influence of halo mass accretion history on galaxy properties and assembly bias
Halo assembly bias is the secondary dependence of the clustering of dark matter haloes on their assembly histories at fixed halo mass. This established dependence is expected to manifest itself on galaxy clustering, a potential effect commonly known as gal ...
OXFORD UNIV PRESS2021Very massive tracers and higher derivative biases
Most of the upcoming cosmological information will come from analyzing the clustering of the Large Scale Structures (LSS) of the universe through LSS or CMB observations. It is therefore essential to be able to understand their behavior with exquisite prec ...
2020Hallucination Engineering: From Neuroscience Robotics to Hallucinations in Health and Disease
My thesis focuses on a psychotic symptom called the presence hallucination (PH). PHs are defined as the false perception that someone is nearby when no one is actually present. PHs can occur in various populations, ranging from healthy subjects (when expos ...
