Anisotropic Phonon Dynamics and Directional Transport in Actinide van der Waals Semiconductor USe
Aljoscha Söll, Valentino Jadrisko, Sourav Dey +13
Direction-dependent charge transport and optical responses are characteristic of van der Waals (vdW) materials with strong in-plane anisotropy. While transition-metal trichalcogeni…
Symbiotic stars in Galactic open clusters
Lukas KueÃ, Ernst Paunzen
The age determination of symbiotic stars is essential to put further constraints on models explaining these binary systems. In the Galactic field, this is especially problematic be…
New Frontiers in the Study of Magnetic Massive Stars with the Habitable Worlds Observatory
Alexandre David-Uraz, Véronique Petit, Coralie Neiner +10
High-mass stars are notable for several reasons: they are characterized by strong winds, which inject momentum and enriched material into their surroundings, and die spectacularly…
Hardness of 4-Colourings G-Colourable Graphs
Sergey Avvakumov, Marek Filakovský, Jakub Opršal +2
We study the complexity of a class of promise graph homomorphism problems. For a fixed graph H, the H-colouring problem is to decide whether a given graph has a homomorphism to H.…
