Molecular knots, left and right: How molecules form knots
Helical molecules, similarly to a corkscrew, have a spiral shape that can be either left- or right-turning. Such "chiral molecules" can collectively organize (assemble) into large left- or right-handed twisted structures. These exhibit special optica.....»»
A precise test of quantum electrodynamics: Measuring the g factor of electrons in hydrogen-like tin
Quantum electrodynamics is the best-tested theory in physics. It describes all electrical and magnetic interactions of light and matter. Scientists at the Max-Planck-Institut für Kernphysik in Heidelberg (MPIK) have now used precision measurements o.....»»
Physicists realize fractionalization without a magnetic field
On the dream list of many condensed matter physicists is observing fractionalization, the phenomena of a collective state of electrons carrying a charge that is a fraction of the electron charge, without a magnetic field......»»

Research: Electrons in a strange metal world
Imagine a flock of birds as they wheel across the sky: surging into a mass, flowing into ribbons that twist and turn again into fantastic shapes. If you follow one bird within the flock, you can describe its actions, the way it flaps its wings or use.....»»
Simulations reveal the atomic-scale story of qubits
Researchers led by Giulia Galli at University of Chicago's Pritzker School of Molecular Engineering report a computational study that predicts the conditions to create specific spin defects in silicon carbide. Their findings, published online in Natu.....»»
Striking rare gold: Researchers unveil new material infused with gold in an exotic chemical state
For the first time, Stanford researchers have found a way to create and stabilize an extremely rare form of gold that has lost two negatively charged electrons, denoted Au2+. The material stabilizing this elusive version of the valued element is a ha.....»»
Scientists observe interaction of components in tire rubber at the atomic scale
Scientists have observed the molecular motion of rubber components typically used in automobile tires—polybutadiene and carbon black—with the world's fastest time resolution......»»
Concave, umbrella-like metal complexes provide space for giant molecular rotors to operate in solid state
Solid materials are generally known to be rigid and unmoving, but scientists are turning this idea on its head by exploring ways to incorporate moving parts into solids. This can enable the development of exotic new materials such as amphidynamic cry.....»»
A breakthrough discovery could accelerate the arrival of controlled fusion energy on Earth
Researchers led by Chang Liu of PPPL have unveiled a promising approach to mitigating damaging runaway electrons created by disruptions in tokamak fusion devices. Key to the approach was harnessing a unique type of plasma wave that bears the name of.....»»
Elk hoof disease likely causes systemic changes
Elk treponeme-associated hoof disease, previously thought to be limited to deformations in elks' hooves, appears to create molecular changes throughout the animal's system, according to epigenetic research from Washington State University......»»
