Physicists discover a quantum state with a new type of emergent particles: Six-flux composite fermions

Feb 21, 2024 16:49 EST

If the fractional quantum Hall regime were a series of highways, these highways would have either two or four lanes. The flow of the two-flux or four-flux composite fermions, like automobiles in this two- to four-flux composite fermion traffic scenario, naturally explains the more than 90 fractional quantum Hall states that form in a large variety of host materials. Physicists at Purdue University have recently discovered, though, that fractional quantum Hall regimes are not limited to two-flux or four-flux and have discovered the existence of a new type of emergent particle, which they are...

'The future is fungal': New research finds that fungi that live in healthy plants are sensitive to climate change

Spruce, pine, fir and other trees tower across the frigid swaths of land that span North America, northern Europe and Russia in a great ring around the world. These boreal forests constitute the largest land ecosystem and the northernmost forests on Earth.

Throwing lithography a curve: Research introduces mask wafer co-optimization method

At the heart of advancing semiconductor chip technology lies a critical challenge: creating smaller, more efficient electronic components. This challenge is particularly evident in the field of lithography, the process used to create intricate patterns on semiconductor materials (called wafers) for the production of chips.

Study finds anti-piracy messages backfire, especially for men

Threatening messages aimed to prevent digital piracy have the opposite effect if you're a man, a new study from the University of Portsmouth has found. According to the research, women tend to respond positively to this kind of messaging, but men typically increase their piracy behaviors by 18%.

James Webb telescope finds ancient galaxy larger than our Milky Way, and it's threatening to upend cosmology

Astronomers believe the first galaxies formed around giant halos of dark matter. But a newly discovered galaxy dating to roughly 13 billion years ago mysteriously appeared long before that process should have occurred.

More frequent extreme droughts result in significant crop losses, say researchers

Climate change has resulted in increasingly extreme weather events worldwide. NIBIO research scientist Pål Thorvaldsen is among the many scientists who participated in a large international drought experiment initiated by the University of Michigan, U.S. He explains that climate change may lead to more frequent occurrences of short-term extreme drought.

Coordination polymer crystals show promise as new generation of light sources for industry, medicine

New forms of the light-emitting materials called phosphors, with enhanced versatility relative to existing options, are being developed by researchers at the National Institute for Materials Science (NIMS) in Japan, with colleagues at Tokyo University of Science and Hokkaido University. Their work is published in the journal Science and Technology of Advanced Materials.
