Turning light upside down

Thu, 02/22/2018 - 1:21pm
Researchers have developed a 'hyperbolic metasurface' on which light propagates with completely reshaped wavefronts. The achievement towards a more precise control and monitoring of light is particularly relevant to the technological challenges of miniaturizing optical devices for sensing and signal processing.

Understanding the wetting of micro-textured surfaces can help give them new functionalities

Thu, 02/22/2018 - 11:50am
The wetting and adhesion characteristics of solid surfaces critically depend on their fine structures. However, until now, our understanding of exactly how the sliding behavior of liquid droplets depends on surface microstructures has been limited. Now, physicists have conducted experimental and theoretical studies on the friction of liquid droplets on micro-structured surfaces.

Developing reliable quantum computers

Thu, 02/22/2018 - 11:50am
Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can't manage. But how do you test a quantum computer to ensure it is working reliably? Depending on the algorithmic task, this could be an easy or a very difficult certification problem. An international team of researchers has taken an important step towards solving a difficult variation of this problem, using a statistical approach.

Quantum recurrence: Everything goes back to the way it was

Thu, 02/22/2018 - 11:50am
When a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles in a container, for example, will return almost exactly to their starting positions after some time. For decades, scientists have investigated how this 'Poincaré Recurrence Theorem' can be applied to the world of quantum physics. Now, researchers have successfully demonstrated a kind of 'Poincaré recurrence' in a multi-particle quantum system.

In a first, tiny diamond anvils trigger chemical reactions by squeezing

Wed, 02/21/2018 - 10:19am
Scientists have turned the smallest possible bits of diamond and other super-hard specks into 'molecular anvils' that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.
