Team maps magnetic fields of bacterial cells, nano-objects for the first time

For the first time, researchers have noted that the magnetic fields of bacterial cells and magnetic nano-objects in liquid can be studied at high resolution using electron microscopy.

Weyl particles detected in strongly correlated electron systems

At TU Wien recently, particles known as 'Weyl fermions' were discovered in materials with strong interaction between electrons. Just like light particles, they have no mass but nonetheless they move extremely slowly.

Physicists find evidence of an exotic state of matter

Using ultracold atoms, researchers at Heidelberg University have found an exotic state of matter where the constituent particles pair up when limited to two dimensions. The findings from the field of quantum physics may hold important clues to intriguing phenomena of superconductivity. The results were published in Science.

Team maps magnetic fields of bacterial cells and nano-objects for the first time

A research team led by a scientist from the U.S. Department of Energy's Ames Laboratory has demonstrated for the first time that the magnetic fields of bacterial cells and magnetic nano-objects in liquid can be studied at high resolution using electron microscopy. This proof-of-principle capability allows first-hand observation of liquid environment phenomena, and has the potential to vastly increase knowledge in a number of scientific fields, including many areas of physics, nanotechnology, biofuels conversion, biomedical engineering, catalysis, batteries and pharmacology.

The origin of water's unusual properties found

Using x-ray lasers, researchers have been able to map out how water fluctuates between two different states when it is cooled. At -44°C these fluctuations reach a maximum pointing to the fact that water can exist as two different distinct liquids.

Now entering, lithium niobate valley

Lithium niobate is already one of the most widely used optical materials, well-known for its electro-optic properties but it is notoriously difficult to fabricate high-quality devices on a small scale using lithium niobate, an obstacle that has so far ruled out practical integrated, on-chip applications. Now, researchers have developed a technique to fabricate high-performance optical microstructures using lithium niobate, opening the door to ultra-efficient integrated photonic circuits, quantum photonics, microwave-to-optical conversion and more.

Quantum coupling

Physicists have linked atoms and superconductors in a key step towards new hardware for quantum computers and networks.

A particle like slow light

Weyl particles are not particles which can move on their own (like electrons or protons), they only exist as 'quasiparticles' within a solid material. Now, for the first time, such Weyl particles has been found in a special kind of material, which is particularly interesting for novel technological applications: scientists have measured Weyl-fermions in a material with highly correlated electrons. Surprisingly, these fermions move very slowly, despite having no mass.

Understanding the impact of defects on the properties of moS2

Highly desired in the petrochemical industry, but generally unwanted in electronics manufacture, defects in MoS2 influence the properties and utility of this material. Analysis of atomically thin MoS2 reveals how defects behave and relate to MoS2's anomalies.

Valleytronics route towards reversible computer

Researchers have discovered a new route towards novel reversible computer by fusing the concepts of valleytronics with digital information processing.
