Four-Particle Electron Family Forms Formerly Unidentified State of Matter

Dissipationless electric energy transport—also called superconductivity—is considered an inspiration for the energy sector. Since its discovery over a century ago, researchers globally have been exploring this distinguished quantum occurrence, which, however, needs the electrons in metals to be cooled to ultra-low temperatures.

Quantum Anomalous Hall Effect Discovered in a Very Simple Material

Theorists at The University of Texas at Dallas, along with colleagues in Germany, have for the first time observed a rare phenomenon called the quantum anomalous Hall effect in a very simple material. Previous experiments have detected it only in complex or delicate materials.

First Experimental Reconstruction of a Bloch Wavefunction

Lightspeed is the fastest velocity in the universe. Except when it isn't. Anyone who's seen a prism split white light into a rainbow has witnessed how material properties can influence the behavior of quantum objects: in this case, the speed at which light propagates.

Large In-Plane Anisotropic Magnetoresistance Observed in a Novel Quantum Spin Hall Insulator

A RMIT-led, international collaboration published this week has observed large in-plane anisotropic magnetoresistance (AMR) in a quantum spin Hall insulator and the spin quantization axis of the edge states can be well-defined.

New Procedure to Build Materials with Specific Topologies or Architectures

A new study by a group of physicists shows how DNA molecules self-organize into adhesive patches between particles in reaction to assembly instructions. The study results provide a proof of principle for a novel way to create materials with well-defined connectivity between the particles.

Selective Manipulation of Electron Spins with Sound

The captured electrons typically absorb light in the visible spectrum, so that a transparent material becomes colored under the presence of such centers, for instance in diamond.
