X-ray Fractional Orbital Angular Momentum from Coherent Magnetic Scattering
P. D. Montgomery, J. S. Woods, M. R. McCarter +10
Artificial spin ice (ASI) based on a square lattice with a topological defect are known to generate orbital angular momentum (OAM) in diffracted X-ray beams. A previous investigati…

Origin of the Unusual Temperature Dependence of the Upper Critical Field of Kagome Superconductor CsV3Sb5: Multiple Bands or van Hove Singularities?
Ramakanta Chapai, Alexei E. Koshelev, Matthew P. Smylie +8
Van Hove singularities (vHs) located close to the Fermi level in Kagome superconductors AV3Sb5 (A = K, Rb, Cs) have profound influence on their electronic and transport characteris…
