Precipitate/matrix heterophase interfaces are characterized with respect to atomic-scale local compositions in two a-Fe-based alloy systems by three-dimensional atom probe microscopy. The proximity histogram method is utilized for determining the compositions of the precipitates, the matrix phase and the Gibbsian interfacial excess of solute. Suitable methods to measure segregation in multicomp...

We employ angle-resolved photoemission to study the electronic structure of atomically uniform films of Ag grown on Ge(111). A new kind of quantum well state is observed near a specific emission direction away from the surface normal. In contrast with the usual quantum well state arising from electron confinement by specular reflections at the surface and interface of the film, the new kind inv...

A complete physical approach to quantum information requires a robust interface among flying qubits, longlifetime memory, and computational qubits. Here we present a unified interface for microwave and optical photons, potentially connecting engineerable quantum devices such as superconducting qubits at long distances through optical photons. Our approach uses an ultracold ensemble of atoms for...

The coherent interaction of solid-state spins with both optical and microwave fields provides a platform for range quantum technologies, such as sensing, microwave-to-optical transduction memories. Rare-earth ions electronic are interesting in this context, but it is challenging to simultaneously efficiently drive transitions over long crystal. In work, we use loop-gap resonator coherently cloc...
