Gravity: We might have been getting it wrong this whole time

Symmetry has been one of the guiding principles in physicists' search for fundamental laws of nature. What does it mean that laws of nature have symmetry? It means that laws look the same before and after an operation, similar ...

Adding memory to pressure-sensitive phosphors

Mechanoluminescence (ML) is a type of luminescence induced by any mechanical action on a solid, leading to a range of applications in materials research, photonics and optics. For instance, the mechanical action can release ...

A new twist on quantum communication in fiber

New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical ...

On the way to quantum networks

Physicists at LMU, together with colleagues at Saarland University, have successfully demonstrated the transport of an entangled state between an atom and a photon via an optic fiber over a distance of up to 20 km—thus ...

Experimental probe of a complete 3-D photonic band gap

A crystal with a 3-D photonic band gap is a powerful tool to control light, with applications for new types of solar cells, sensors and miniature lasers. Inside a man-made crystal like this, a range of light wavelengths is ...

Wannier90 program becomes community code in major new release

Wannier functions were first introduced by Gregory Wannier in 1937 as an alternative way of describing the electronic ground state of periodic systems. They were linked to Bloch orbitals, the standard method of describing ...

Mapping the path of climate change

Since 1880, the Earth's temperature has risen by 1.9 degrees Fahrenheit and is predicted to continue rising, according to the NASA Global Climate Change website. Scientists are actively seeking to understand this change and ...

Creating and observing current vortices in 2-D materials

Researchers at the University of Chicago and the U.S. Department of Energy's Argonne National Laboratory have developed a new method to measure how photocurrents flow in a 2-D material—a result that could have implications ...

Physicists trap light in nanoresonators for record time

An international team of researchers from ITMO University, the Australian National University, and Korea University have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator a few hundred nanometers ...

Acousto-optic modulation of photonic bound state in the continuum

Applying bound states in the continuum (BICs) in photonic integrated circuits enables low-loss light guidance and routing in low-refractive-index waveguides on high-refractive-index substrates. Here, we demonstrate high-quality ...
