Skyrmions are nanometer- to micrometer-sized magnetic whirls that exhibit particle-like properties and can be moved efficiently by electrical currents. These properties make skyrmions an excellent ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

Astrophysicist Tomoaki Matsumoto and collaborators have used three-dimensional magnetohydrodynamic supercomputer simulations ...

Black holes are one of the most enigmatic stellar objects. While best known for swallowing up their surroundings into a gravity pit from which nothing can escape, they can also shoot off powerful jets ...

Programmable quantum computers have the potential to efficiently simulate increasingly complex molecular structures, electronic structures, chemical reactions, and quantum mechanical states in ...

A new simulation of the galaxy’s magnetic turbulence shakes up how we think about—and visualize—the astrophysical environments. The model was developed by James Beattie, a postdoctoral fellow at the ...

Available at no cost, the online simulation resource offers high accuracy and configurability for magnetic position-sensor design, covering both linear and rotary modes of operation. In order to ...

A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

Swarms of soft microrobots controlled by minimally invasive magnetic fields show promise as biomedical agents. The collective behaviour of such swarms, governed by magnetic and hydrodynamic ...

Magneto-optical microscope image of a skyrmion, which is the dark spot marked by a blue circle, in a ring of magnetic material. The spatially resolved pinning potential, which determines the special ...
