Metasurfaces for broadband quadratic phase Ultra-thin metasurfaces with a specific multi-resonant response can enable simultaneously arbitrarily strong and arbitrarily broadband dispersion compensation, pulse (de)chirping, & compression or broadening with low loss.
Tuning Magnetic Topological Insulators using Defects Inelastic neutron scattering experiments reveal that magnetism in stoichiometric and lightly doped magnetic topological insulators in the Sb2Te3-MnSb2Te4 family is controlled by universal interactions between magnetic defects.
Orbital Fluctuations Control the Magnetism of a Topological Metal Initiation of a spin-reorientation in TbMn6Sn6 by Tb orbital fluctuations revealed by inelastic neutron scattering (INS) experiments.
Chlorination of 2D Silicon Revealed by NMR Solid-state nuclear magnetic resonance (NMR) spectroscopy methods to detect chlorine atoms were developed and showed that 20% of the silicon atoms in 2D silicon nanosheets are chlorine terminated.
