Visual observation of photonic Floquet–Bloch oscillations

Recently, the exploration of Bloch oscillations (BOs) in periodically driven quantum systems, equivalent to "Floquet systems," has drawn tremendous attention because their exotic characteristics are profoundly distinct from ...

New phononics materials may lead to smaller, more powerful wireless devices

What if your earbuds could do everything your smartphone can do already, except better? What sounds a bit like science fiction may actually not be so far off. A new class of synthetic materials could herald the next revolution ...

Laser printing on fallen tree leaves produces sensors for medical and laboratory use

Fabrication of sensors by 3D printing combines speed, freedom of design, and the possibility of using waste as a substrate. Various results have been obtained in a circular economy mode, whereby residues usually thrown away ...

Scientists demonstrate the potential of electron spin to transmit quantum information

The spin of the electron is nature's perfect quantum bit, capable of extending the range of information storage beyond "one" or "zero." Exploiting the electron's spin degree of freedom (possible spin states) is a central ...

The interference of many atoms, and a new approach to boson sampling

In daily life, when two objects are "indistinguishable," it's due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep track of which ball is which as they are ...

Strictly no dancing: Researchers discover 'new molecular design rules'

Since the discovery of quantum mechanics more than a hundred years ago, it has been known that electrons in molecules can be coupled to the motion of the atoms that make up the molecules. Often referred to as molecular vibrations, ...
