The phonon thermal Hall angle in black phosphorus
The origin of phonon thermal Hall Effect (THE) observed in a variety of insulators is yet to be identified. Here, we report on the observation of a thermal Hall conductivity in a non-magnetic elemental insulator, with an amplitude exceeding what has been previously observed. In black phosphorus (BP), the longitudinal ($\kappa_{ii}$), and the transv...

$$CO_2$$ footprint minimization of solar-powered HALE using MDO and eco-material selection
Abstract Multidisciplinary Design Optimization (MDO) enables one to reach a better solution than by optimizing each discipline independently. In particular, the optimal structure of a drone varies depending on the selected material. The $$CO_2$$ C O 2 footprint of a solar-powered High Altitude Long Endurance (HALE) drone is optimized here, where th...
Investigating the electronic states of UTe2 using X-ray spectroscopy
Abstract The recent discovery of superconductivity in paramagnetic UTe 2 turns spotlight on a serious candidate for spin-triplet state. To draw a complete picture of the superconducting state in UTe 2 precise knowledge of the electronic properties of the 5 f states of Uranium is missing. We report on x-ray absorption and magnetic circular dichroism...
Thickness and Roughness Effect of Pr2NiO4+δ Coating on the Normal Spectral Emittance
Pr2 NiO(4+δ) coatings of rare earth nickelate oxide were prepared through RF magnetron co-sputtering, combined with an appropriate heat treatment. The study focused on optimizing the growth conditions to enhance the thermal emittance of the coatings, taking into account the influence of thickness and roughness. The research findings revealed intere...
Frozen sound: An ultra-low frequency and ultra-broadband non-reciprocal acoustic absorber
Abstract The absorption of airborne sound is still a subject of active research, and even more since the emergence of acoustic metamaterials. Although being subwavelength, the screen barriers developed so far cannot absorb more than 50% of an incident wave at very low frequencies (
Induced photoelectron circular dichroism onto an achiral chromophore
An achiral chromophore can acquire a chiral spectroscopic signature when interacting with a chiral environment. This so-called induced chirality is documented in electronic or vibrational circular dichroism, which arises from the coupling between electric and magnetic transition dipoles. Here, we demonstrate that a chiroptical response is also indu...
