Findings from Hokkaido University in the Area of Low Dimensional Structures Described

February 18, 2014

By a News Reporter-Staff News Editor at Physics Week -- Research findings on Low Dimensional Structures are discussed in a new report. According to news reporting out of Hokkaido, Japan, by VerticalNews editors, research stated, "We discuss Andreev bound states appearing at the interface between two different superconductors characterized by different nontrivial topological numbers such as one-dimensional winding numbers and Chern numbers. The one-dimensional winding number characterizes d(xy) and p(x) wave superconductors."

Our news journalists obtained a quote from the research from Hokkaido University, "The Chern number characterizes chiral superconductors. The number of interfacial bound states at the zero-energy is equal to the difference between the topological numbers on either sides of the Josephson junction."

According to the news editors, the research concluded: "We also discuss relation between properties of the Andreev bound states at the zero-energy and features of Josephson current at low temperature."
