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.

Combining two spin-dependent effects generates a microwave signal that can be easily read to study the magnetization dynamics in a device with novel geometry.

Time-reversing the signals generated by a nonlinear element could form the basis of a new secure communications protocol in the midst of chaotic waves.

Nanoscale engineering of multiferroic thin films enables electric control of a device’s interface magnetism, thus offering a promising prospective for ultralow power spintronics.

Microwave signals in an entangled state can be generated and then spatially separated on a single chip, enabling quantum communication with microwave technology.

Experimental data in combination with calculations show why some organic semiconductors have intrinsically different mobilities for electrons and holes.

New experiments on an organic ferroelectric verify that its electric polarization is driven primarily by an electron shift, rather than the ion shift that characterizes most other ferroelectrics.
