An international group of researchers has created a mixed magnon state in an organic hybrid perovskite material by utilizing the Dzyaloshinskii-Moriya-Interaction (DMI). The resulting material has potential for processing and storing quantum computing information. The work also expands the number of potential materials that can be used to create hybrid magnonic systems.

In magnetic materials, quasi-particles called magnons direct the electron spin within the material. There are two types of magnons — optical and acoustic — which refer to the direction of their spin.

“Both optical and acoustic magnons propagate spin waves in antiferromagnets,” says Dali Sun, associate professor of physics and member of the Organic and Car...

Earth’s magnetic field does more than keep everyone’s compass needles pointed in the same direction. It also helps preserve Earth’s sliver of life-sustaining atmosphere by deflecting high energy particles and plasma regularly blasted out of the sun...

Harmful intestinal inflammation might be prevented with a one-two punch. Fresh insights into how our bodies interact with the microbes living in our guts suggest that a two-drug combination may offer a new way to treat inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis.

The potential treatment pathway emerges from a study led by experts at Cincinnati Children’s published online March 28, 2023, in the Journal of Experimental Medicine. Co-first authors were Garrett Overcast, PhD, and Hannah Meibers, BS. Corresponding author was Chandrashekhar Pasare, DVM, PhD, Division of Immunobiology and co-director, Center for Inflammation and Tolerance.

The research team conducted numerous experiments to learn about how immune cells located in the lining of the intestin...

Erasing data perfectly and reaching the lowest possible temperature — those two things seem to be completely different, but they are closely intertwined. The absolute lowest temperature possible is -273.15 degrees Celsius. It is never possible to cool any object exactly to this temperature — one can only approach absolute zero. This is the third law of thermodynamics.

A research team at TU Wien (Vienna) has now investigated the question: How can this law be reconciled with the rules of quantum physics? They succeeded in developing a “quantum version” of the third law of thermodynamics: Theoretically, absolute ze...
