Laser-Sharp Look at Spinning Electrons Sets the Stage for New Physics Discoveries
Spin is an intrinsic property of the electron. When electrons spin in the same direction at a given time, the quantity is called polarization. Understanding polarization helps examine the structure of nuclei of heavy elements. Now, nuclear physicists have measured the polarization of an electron beam more precisely than ever before.

An atomic-scale window into superconductivity paves the way for new quantum materials
Superconductors are materials with no electrical resistance whatsoever, commonly requiring extremely low temperatures. They are used in a wide range of domains, from medical applications to a central role in quantum computers. Superconductivity is caused by specially linked pairs of electrons known as Cooper pairs. So far, the occurrence of Cooper pairs has been measured indirectly macroscopically in bulk, but a new technique developed by researchers at Aalto University and Oak Ridge National Laboratories in the US can detect their occurrence with atomic precision.

One-dimensional red phosphorous glows in unexpected ways
In a study published in Nature Communications, an international team led by Aalto University researchers has found that fibrous red phosphorous, when electrons are confined in its one-dimensional sub-units, can show large optical responses – that is, the material shows strong photoluminescence under light irradiation. Red phosphorous, like graphene, belongs to a unique group of materials discovered in 2017 called one-dimensional van der Waals (1D vdW) materials.

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.
