Euclid preparation. The shape of halo profiles in CDM and non-standard cosmologies

Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304

We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…

Wave chirality reversal without passing achirality

M. V. Berry, K. Y. Bliokh, J. M. Robbins

Chiral connectedness describes chiral structures that transform smoothly into their mirror images while never being achiral. The phenomenon is illustrated with a two-parameter fami…

Quantum-geometric bounds on Casimir repulsion

Adolfo G. Grushin

The quantum geometric tensor has been shown to bound the gap, optical absorption, and dielectric susceptibilities of materials. Here we derive new quantum-geometric bounds on the m…

Green's function theory of magnetism in BiCuO: anisotropic Heisenberg XYZ model

R. O. Kuzian, E. E. Krasovskii

The Green's function theory of Lymar' and Rudoi [Theor. Math. Phys. vol. 21, 990 (1974)] is generalized to the case of multiple intra- and inter-sublattice magnetic interactions in…

Photoemission insights into lanthanide-based crystals

Dmitry Yu. Usachov, Georg Poelchen, Vasily S. Stolyarov +3

The interplay of strongly localized 4 electrons with itinerant spd-valence states gives rise to a wide range of correlated phenomena and properties that place lanthanide materia…

Giant Exfoliation Induced Magnetic Coercivity in FeGaTe

Lingrui Mei, PeiYu Cai, Sang-Eon Lee +6

Permanent magnets with strong anisotropy and high coercivity underpin modern information and energy technologies, yet rare-earth-free alternatives remain limited. Here, we show tha…
