A magnetic twist to graphene

By combining ferromagnets and two rotated layers of graphene, researchers open up a new platform for strongly interacting states using graphene's unique quantum degree of freedom.

The direct observation of the Pauli principle

The Pauli exclusion principle is a law of quantum mechanics introduced by Austrian physicist Wolfgang Pauli, which offers valuable insight about the structure of matter. More specifically, the Pauli principle states that two or more identical fermions cannot simultaneously occupy the same quantum state inside a quantum system.

Neutrinos, atomic clocks and an experiment to detect a time dilation

Griffith University researchers are conducting an experiment at ANSTO that will test a revolutionary physics theory that time reversal symmetry-breaking by neutrinos might cause a time dilation at the quantum scale.

New microscopy concept enters into force

The first demonstration of an approach that inverts the standard paradigm of scanning probe microscopy raises the prospect of force sensing at the fundamental limit.

Breakthrough in quantum photonics promises a new era in optical circuits

Researchers have shown that single photons can be emitted in a uniform way from quantum dots arranged in a precise pattern. The team has used such methods to create single-quantum dots, with their remarkable single-photon emission characteristics. It is expected that the ability to precisely align uniformly-emitting quantum dots will enable the production of optical circuits, potentially leading to novel advancements in quantum computing and communications technologies.

New fiber optic temperature sensing approach to keep fusion power plants running

The pursuit of fusion as a safe, carbon-free, always-on energy source has intensified in recent years, with a number of organizations pursuing aggressive timelines for technology demonstrations and power plant designs. New-generation superconducting magnets are a critical enabler for many of these programs, which creates growing need for sensors, controls, and other infrastructure that will allow the magnets to operate reliably in the harsh conditions of a commercial fusion power plant.

Imaging technique provides link to innovative products

A study announces the successful use of a new nanoimaging technique that will allow researchers to test and identify two-dimensional materials.

Switching nanolight on and off

The report demonstrates a new method to control the flow of light of nanolight. Optical manipulation on the nanoscale, or nanophotonics, has become a critical area of interest as researchers seek ways to meet the increasing demand for technologies that go well beyond what is possible with conventional photonics and electronics.

optical coating can simultaneously reflect and transmit the same wavelength, or color

The technology, based on Fano resonance, results in a coating that fully reflects only a very narrow wavelength. The technology could improve the effectiveness of devices that use hybrid thermal-electric power generation as a solar energy option.

Molecule from nature provides fully recyclable polymers

Plastics are among the most successful materials of modern times. However, they also create a huge waste problem. Scientists produced different polymers from lipoic acid, a natural molecule. These polymers are easily depolymerized under mild conditions. Some 87 percent of the monomers can be recovered in their pure form and re-used to make new polymers of virgin quality.
