Chiral zero sound found in Weyl semimetals

A pair of researchers at the Hong Kong University of Science and Technology has found that a chiral zero sound (CZS) effect can be induced in Weyl semimetals. In their paper published in the journal Physical Review Letters, ...

New membrane efficiently separates mirrored molecules

Prof. Liu Bo and colleagues at the University of Science and Technology of China (USTC) have developed a chiral separation membrane capable of capturing left-handed chiral molecules and releasing the right-handed counterpart ...

Approaching the magnetic singularity

In many materials, electrical resistance and voltage change in the presence of a magnetic field, usually varying smoothly as the magnetic field rotates. This simple magnetic response underlies many applications including ...

Manipulating electron spin using artificial molecular motors

Artificial molecular switches and machines have undergone rapid advances over the past several decades. Particularly, artificial molecular motors are highly attractive from the viewpoint of chirality switching during rotational ...

New material also reveals new quasiparticles

Researchers at PSI have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. In the symmetrically ...

A microlaser emitting helical light

Researchers recently demonstrated the realization of an integrated microlaser based on a novel design that emits light in chiral modes, thus producing corkscrews of light. An object is said to be chiral if it can be distinguished ...

Graphene and cobalt for creating new electromagnetic devices

Researchers from IMDEA Nanociencia and other European centres have discovered that the combination of graphene with cobalt offers relevant properties in the field of magnetism. This breakthrough sets the stage for the development ...
