A new technique for powering medical implants wirelessly could allow them to shrink to sub-millimeter sizes in the future, according to theory and simulations.

Researchers propose a way to transfer quantum information between ions and electronic circuits, opening up new options for quantum computation.

Improvements in a new device suggest that electron spins could be harnessed to make a better clock for silicon chips.

A quantum mechanical effect seems to explain amplification in a component that might replace transistors in nanoscale circuits.

A proposed ‘thermal rectifier’ would conduct heat preferentially in one direction.

A single-atom bridge proves that the irreducible unit of current between two superconductors can be many times the charge of the electron.

A new theory will help researchers understand and harness a new low-cost technique for getting electrons to leave a surface. An improved flat panel display may be the result.

By ‘writing’ and ‘erasing’ molecule-sized bits of a thin organic film, physicists have demonstrated its potential to become the next high-density storage medium.
