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 ...

Binding together repelling atoms

Basic chemistry tells us that a bond between atoms can form if it is energetically more favorable for the atoms to stick together than staying apart. This fundamentally requires an attractive force between the atoms. However, ...

Probing electron behaviour at the tips of nanocones

One of the ways of improving electrons manipulation is though better control over one of their inner characteristics, called spin. This approach is the object of an entire field of study, known as spintronics. Now, Richard ...

New scales for the new kilogram

The Planck scale works according to the principle of electromagnetic force compensation: A weight force on one side of the scale is balanced by an electromagnetic force on the other side. This means that weights (so-called ...

Scientists explain the paradox of quantum forces in nanodevices

Researchers from the Peter the Great St. Petersburg Polytechnic University (SPbPU) have proposed a new approach to describe the interaction of metals with electromagnetic fluctuations (i.e., with random bursts of electric ...
