Disorder-induced optical transition from spin Hall to random Rashba effect Disordered structures give rise to intriguing phenomena owing to the complex nature of their interaction with light. We report on photonic spin-symmetry breaking and unexpected spin-optical transport phenomena arising from subwavelength-scale disordered g

Monitoring and manipulating Higgs and Goldstone modes in a supersolid quantum gas Higgs and Goldstone modes are collective excitations of the amplitude and phase of an order parameter that is related to the breaking of a continuous symmetry. We directly studied these modes in a supersolid quantum gas created by coupling a Bose-Einstein

Activation of surface lattice oxygen in single-atom Pt/CeO2 for low-temperature CO oxidation To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of heat wasted in the exhaust. Hence, future generations of catalysts must perform at temperatures that are 100°C lower than current exhaust-treatment ca

Reducing the stochasticity of crystal nucleation to enable subnanosecond memory writing Operation speed is a key challenge in phase-change random-access memory (PCRAM) technology, especially for achieving subnanosecond high-speed cache memory. Commercialized PCRAM products are limited by the tens of nanoseconds writing speed, originating fro

Synthesis of ultrasmall, homogeneously alloyed, bimetallic nanoparticles on silica supports Supported nanoparticles containing more than one metal have a variety of applications in sensing, catalysis, and biomedicine. Common synthesis techniques for this type of material often result in large, unalloyed nanoparticles that lack the interactions b

Eudicot plant-specific sphingolipids determine host selectivity of microbial NLP cytolysins Necrosis and ethylene-inducing peptide 1–like (NLP) proteins constitute a superfamily of proteins produced by plant pathogenic bacteria, fungi, and oomycetes. Many NLPs are cytotoxins that facilitate microbial infection of eudicot, but not of monoco
