The power of attraction: Magnets in particle accelerators

In 1820, Hans Christian Oersted gave a demonstration on electricity to a class of advanced students at the University of Copenhagen in Denmark. Using an early battery prototype, he looked to see what effect an electric current ...

More than a spring-clean for LHC magnets

In April, work began on one of the major projects scheduled for the second long shutdown (LS2) of the CERN accelerators: improving the electrical insulation of over 1200 magnets in the Large Hadron Collider (LHC). To complete ...

How spin dances with dipole

The key physical property of multiferroic materials is the existence of a coupling between magnetism and polarization. The origin and manifestations of magnetoelectricity can be very different in the available multiferroic ...

In a new quantum simulator, light behaves like a magnet

Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at ...

The atomic dynamics of rare everlasting electric fields

By ricocheting neutrons off the atoms of yttrium manganite (YMnO3) heated to 3,000 degrees Fahrenheit, researchers have discovered the atomic mechanisms that give the unusual material its rare electromagnetic properties. ...

Team simulates a magnetar to seek dark matter particle

MIT physicists are proposing a new experiment to detect a dark matter particle called the axion. If successful, the effort could crack one of the most perplexing unsolved mysteries in particle physics, as well as finally ...
