Spin filter for arbitrary spins by substrate engineering
We design spin filters for particles with potentially arbitrary spin S (=1/2, 1, 3/2, ...) using a one-dimensional periodic chain of magnetic atoms as a quantum device. Describing the system within a tight-binding formalism we present an analytical method to unravel the analogy between a one-dimensional magnetic chain and a multi-strand ladder network. Our scheme is applicable to ultracold quantum gases, and might inspire future experiments in this direction.
Growth of Large Crystalline Grains of Vanadyl-Phthalocyanine without Epitaxy on Graphene
Graphene’s flat, homogeneous surface can encourage the growth of large organic semiconducting crystals without relying on epitaxy: a promising development for its application as an electrode material.
Solar cycle variation of energy in the solar wind
The solar wind flows away from the Sun, depositing energy into the magnetosphere as it reaches Earth. Here we explore various ways of quantifying this energy and its variation over the last 20 years.
