Calculating quantum vacuum forces in nanostructures

(Phys.org)—One of the surprising predictions of quantum mechanics is that uncharged conductors can attract each other over small distances, even in empty space. While the resulting "Casimir force" has been accurately measured ...

Magnetic fields created before the first stars

Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has been researched by Prof. Dr. Reinhard ...

Transforming noise into mechanical energy at nano level

A team of researchers at the Freie Universität Berlin, co-ordinated by José Ignacio Pascual, have developed a method that enables efficiently using the random movement of a molecule in order to make a macroscopic-scale ...

'Dark plasmons' transmit energy

Microscopic channels of gold nanoparticles have the ability to transmit electromagnetic energy that starts as light and propagates via "dark plasmons," according to researchers at Rice University.

Dutch team has solution for troubled ITER nuclear fusion reactor

(PhysOrg.com) -- The superconducting cables designed for the ITER fusion reactor (cost: 16 billion euros = $21.2 billion) are unable to withstand the planned forty to sixty thousand charge cycles. Barring a solution, the ...

Nature's laws may vary across the Universe
