Magnetism Meets Topology on a Superconductor’s Surface

Scientists have found an energy band gap—an energy range where no electrons are allowed—opens at a point where two allowed energy bands intersect on the surface of an iron-based superconductor. This unusual electronic energy structure could be used for quantum information science and electronics.

Scientists develop forecasting technique that could help advance quest for fusion energy

An international group of researchers has developed a technique that forecasts how tokamaks might respond to unwanted magnetic errors. These forecasts could help engineers design fusion facilities that create a virtually inexhaustible supply of safe and clean fusion energy to generate electricity.

Quantum Materials Quest Could Benefit From Graphene That Buckles

Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.

Scientists Dive Deep Into Hidden World of Quantum States

A research team led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a technique that could lead to new electronic materials that surpass the limitations imposed by Moore’s Law.

ORNL neutrons add advanced polarization capability for measuring magnetic materials

Neutron scattering instruments at ORNL’s HFIR and SNS are undergoing upgrades which will enable them to study magnetic phenomena previously not possible in the US. Incorporating a device for spherical neutron polarimetry enables the ability to characterize complex magnetic systems in new dimensions for materials that could be developed for enhanced data storage and quantum computing technologies.

How a Magnet Could Help Boost Understanding of Superconductivity

Physicists have unraveled a mystery behind the strange behavior of electrons in a ferromagnet, a finding that could eventually help develop high temperature superconductivity. A Rutgers co-authored study of the unusual ferromagnetic material appears in the journal Nature.
