Researchers generate tunable twin particles of light

Identical twins might seem 'indistinguishable,' but in the quantum world the word takes on a new level of meaning. While identical twins share many traits, the universe treats two indistinguishable quantum particles as intrinsically ...

In-plane antiferromagnets host a rich class of particle-like spin textures

Compared with the chiral spin textures in ferromagnets, their antiferromagnetic counterparts can be manipulated by spin currents with a more direct approach due to the absence of the skyrmion Hall effect, and much lower power ...

New malaria protein structure upends theory of how cells grow and move

Researchers from the Walter and Eliza Hall Institute have overturned conventional wisdom on how cell movement across all species is controlled, solving the structure of a protein that cuts power to the cell 'motor'. The protein ...

A magnetic twist to graphene

Electrons in materials have a property known as 'spin," which is responsible for a variety of properties, the most well-known of which is magnetism. Permanent magnets, like the ones used for refrigerator doors, have all the ...

Observation of skyrmions in a ferromagnet with centrosymmetry

Researchers from the National Institute of Materials Science (NIMS) have used Lorentz electron microscopy to show that magnetic skyrmions are spontaneously formed as nanomagnetic clusters in a ferromagnetic manganese oxide ...

3D sound for the Zurich Opera House

With the audio software SpatialSound Wave from Fraunhofer, sounds can be positioned freely in the room, so that visual and acoustic events coincide realistically. In the Zurich Opera House the three-dimensional sound has ...

Study unveils an antiferromagnetic metal phase in an electron-doped rare-earth nickelate

Researchers at Harvard University, the Lawrence Berkeley National Laboratory, Arizona State University, and other institutes in the United States have recently observed an antiferromagnetic metal phase in electron-doped NdNiO3 ...

The observation of Bloch ferromagnetism in composite fermions

Composite fermions are exotic quasi-particles found in interacting 2-D fermion systems at relatively large perpendicular magnetic fields. These quasi-particles, which are composed of an electron and two magnetic flux quanta, ...

Understanding the mechanism for generating electric current without energy consumption at room temperature

A group of researchers in Japan and China identified the requirements for the development of new types of extremely low power consumption electric devices by studying Cr-doped (Sb, Bi)2Te3 thin films. This study has been ...

Scientists propose 3D graphene-like 'hyper-honeycomb' structures

(Phys.org)—Scientists have proposed a new family of structures that are three-dimensional (3D) variations of graphene, the simplest example of which is called a "hyper-honeycomb." If the proposed structures can be experimentally ...
