Light can now be used to achieve ever better control of microparticles and nanoparticles. Read More...

Quantum gas in a laser cage the korber european science prize 2013 goes to Immanuel Bloch
14 06 13

The German physicist is to be honoured for his ground breaking work in the field of quantum simulation with ultra-cold atoms. Read More...

Quantum invisibility cloak hides objects from reality
13 06 13

Hongsheng Chen at Zhejiang University in China and an international circle of friends have created large-scale invisibility cloaks that work over the entire optical spectrum but can cloak in several directions at once. Read More...

Nanotechnology exploring the secret of knots
10 06 13

Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. Read More...

Dense hydrogen in a new light
04 06 13

Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich planets Read More...

Carbon nanotubes make ultra thin saw
02 08 13

You can’t saw without producing sawdust – and that can be expensive if, for example, the “dust” comes from wafer manufacturing in the photovoltaic and semiconductor industries... Read More...

Quantum simulation of low temperature metallic hydrogen
02 07 13

Theoretical techniques have been used to predict the existence of metallic liquid hydrogen at low temperature and high pressure in a paper published in Nature Communications. Read More...

Particle accelerator that can fit on a tabletop opens new chapter for science research
21 06 13

Tabletop device achieves energy and focus that has previously required a conventional accelerator that stretches more than the length of 2 football fields. Read More...

Discovery of new material state counterintuitive to laws of physics
13 06 13

At the suburban Chicago laboratory, a group of scientists has seemingly defied the laws of physics and found a way to apply pressure to make a material expand instead of compress/contract. Read More...

Testing artificial photosynthesis
12 06 13

With the daily mean concentrations of atmospheric carbon dioxide having reached 400 parts-per-million for the first time in human history, the need for carbon-neutral alternatives to fossil fuel energy has never been more compelling. Read More...

First observation of spin hall effect in a quantum gas is step toward atomtronics
06 06 13

Researchers have reported the first observation of the 'spin Hall effect' in a Bose-Einstein condensate, a cloud of ultracold atoms acting as a single quantum object. Read More...

Friction in the nano world. Physicists discover a new kind of friction
31 05 13

Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material wear Read More...

How Does Hydrogen Metallize
31 07 13

Hydrogen is deceptively simple. It has only a single electron per atom, but it powers the sun and forms the majority of the observed universe. Read More...

Excited but cold Scientists unveil the secret of a reaction for prebiotic synthesis of organic matter
25 06 13

How is it that a complex organism evolves from a pile of dead matter? Read More...

Penetrating the quantum nature of magnetism
19 06 13

Antiferromagnets are materials that lose their apparent magnetic properties when cooled down close to absolute zero temperature. Read More...

New Quantum Dot Technique Combines Best of Optical and Electron Microscopy
13 06 13

It's not reruns of "The Jetsons," but researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture... Read More...

The Dance of the atoms
12 06 13

Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in. Atoms on iron-oxide surfaces behave in a similar way: Only with the right molecular partner do they dance across the surface. Read More...

Spintronics approach enables new quantum technologies
05 06 13

A team of researchers, including members of the University of Chicago’s Institute for Molecular Engineering, highlight the power of emerging quantum technologies in two recent papers published in the Proceedings of the National Academy of Sciences Read More...

Klein tunneling Coupled particles cross energy wall
30 05 13

A new model demonstrates that it is possible for two particles to cross an energy barrier together, where a single particle could not. Read More...
