Researchers at Monash University have developed a new X-ray imaging technique that can image two overlapping samples at the same time, potentially doubling scanning efficiency while opening new possibilities for industrial inspection and scientific research. Go to Source An electron is supposed to be indivisible. It carries one fundamental unit of electric charge, and every electron is exactly the same. But under extreme conditions, large numbers of electrons act together and give rise to new quantum objects called quasiparticles. These act as if they carry only a fraction of an electron’s charge, making […] A new study published in Science Advances takes a closer look at how AI agents’ choices are influenced by their peers. The team found that more advanced models tend to follow the majority when shown other agents’ choices, and they maintain stable agreement in groups far larger than those seen in humans. Go to Source […] A study has been published in Nature Communications that identifies an unusual regime of quantum oscillations in a three-dimensional topological insulator. The results show that, when subjected to temperatures near absolute zero and extreme magnetic fields, electrons in the material zirconium pentatelluride (ZrTe₅) exhibit behavior that deviates from the pattern predicted by conventional theory. Go […] Researchers at Rice University have found that gently squeezing a crystal of iron sulfide can change two of its unusual properties at the same time: its tiny magnetic signal and the way electricity moves through it. The result gives scientists a clearer picture of how a newly recognized class of magnetic materials works and suggests […] Time-reversal symmetry is an exotic behavior found in systems whose internal physics looks different when running forward versus backward in time. For some time, physicists have searched for this behavior in systems with almost no overall magnetization. Such phases are highly prized for spintronics, where information is carried using the quantum spins of electrons. Go […] The strongest glasses have an Achilles’ heel that causes them to fail catastrophically when pushed past their limit. They do not bend or stretch, as all damage concentrates into a single plane and the material fails in an instant. This brittleness has long capped the usefulness of high-stability amorphous solids, from bulk metallic glasses to […] Theoretical physicists have long predicted the existence of millicharged particles (mCPs), hypothetical particles that carry a very small electric charge. These particles are expected to interact very weakly with ordinary matter and electromagnetic fields; hence, they would be difficult to detect in conventional particle physics experiments. Go to Source Many fascinating phases in quantum materials emerge when electrons, atoms and other microscopic components begin to act collectively. But these phases do not necessarily appear out of nowhere when a material crosses a transition temperature. Before long-range order develops, microscopic fluctuations can already be present. Go to Source Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside these devices, however, can damage materials that surround the superheated, electrically charged plasma where the nuclear fusion reaction takes place. Go to Source […] Over the past two decades, photonic-crystal surface-emitting lasers (PCSELs) have shown promise as a type of advanced semiconductor laser useful in defense- and aerospace-related applications. Typically, these devices are made with photonic crystal patterns that repeat across the area of the device. But new research from the lab of electrical and computer engineering professor Kent […] Basic biology courses teach that cells contain organelles—such as the nucleus, mitochondria and Golgi apparatus—set apart by lipid membranes to get things done. Recent cell biology research has revealed another organizational principle at work in cells across all orders of biology. Go to Source When one mentions “waves,” we immediately think of a perturbation that propagates. This applies to waves on the shore, sound waves in the air or electromagnetic waves that we use to transmit information via optical fibers. The same idea of propagating perturbations applies to gravitational waves (GWs), which entered the mainstream media a decade ago […] A new pathway has opened for controlling the rotation direction of light simply by changing how molecules are arranged, without having to synthesize complex new materials. Circularly polarized light is a special form of light that travels while rotating like a pinwheel to the left or right. Because different rotation directions can carry different information, […] A research team has developed a new theoretical framework that can suppress light scattering in certain directions while enhancing it in others, even in irregularly arranged materials. The work extends research on controlling light scattering, which has traditionally centered on ordered crystal structures, into the realm of disordered systems. Go to Source […] |
