Scientists discover quantum interference observed within single reaction path
1+ mon, 5+ day ago (68+ words) A research team led by Prof. YUAN Kaijun from the Dalian Institute of Chemical Physi University, has revealed quantum interference between direct and indirect reaction pathways in the photodissociation of partially deuterated water (HOD). These observed dynamical signatures further demonstrate…...
Scientists discover bizarre new states inside tiny magnetic whirlpools
1+ mon, 3+ day ago (457+ words) "These magnons can transmit information through a magnet without the need for charge transport," explains project leader Dr. Helmut Schulthei" from the Institute of Ion Beam Physics and Materials Research at HZDR. "This capability makes them highly attractive for research…...
A tiny twist creates giant magnetic skyrmions in 2 D crystals
1+ mon, 4+ week ago (246+ words) Now researchers report in Nature Nanotechnology that magnetism can also behave in surprising ways under these conditions. In twisted antiferromagnetic layers, magnetic spin patterns are not limited to the small repeating moir" unit cell. Instead, they can spread into much…...

Femtosecond-laser fabrication of micro-supercapacitors with graphene hybrid nanostructured electrodes
2+ mon, 3+ week ago (552+ words) Planar micro-supercapacitors (P-MSCs), by jointly optimizing electrode intrinsic properties and interfacial structural design, serve as promising electrochemical components for next-generation micro-energy storage systems. Towards this goal, scientists in China proposed a universal strategy that integrates femtosecond laser plasma lithography with…...
Twisted 2 D magnet creates skyrmions for ultra dense data storage
2+ mon, 2+ week ago (294+ words) Chromium iodide belongs to a category known as two-dimensional (2 D) materials, which consist of only a few atomic layers arranged in a crystal structure. These ultra thin materials are known to behave very differently from their thicker, three-dimensional versions. Quantum Sensing…...
Physicists finally see strange magnetic vortices predicted 50 years ago
1+ mon, 3+ week ago (412+ words) The newly observed sequence involves two important changes in magnetic behavior that occur as certain materials are cooled toward absolute zero. While scientists have previously detected each transition separately, this study is the first to observe the entire sequence unfolding…...
A quantum discovery that breaks the rules of heating
3+ mon, 3+ week ago (756+ words) In everyday experience, applying repeated force almost always leads to heating. Rubbing your hands together warms your skin. Striking metal with a hammer makes it hot to the touch. Even without formal physics training, people quickly learn a basic rule:…...
New computational model identifies origin of complex magnetization reversal in soft magnets
1+ week, 3+ day ago (266+ words) New model uses persistent homology to analyze topological features in data and extract inhomogeneous structural features from the domain images. Entropy-extended free energy landscape reveals magnetization reversal in maze domains. The explainable entropy-feature-e Xtended Ginzburg-Landau (e X-GL) model maps complex…...
