Loop quantum gravity theory offers glimpse beyond the event horizon

In principle, nothing that enters a black hole can leave the black hole. This has considerably complicated the study of these mysterious bodies, which generations of physicists have debated since 1916, when their existence ...

Three 'twisted' photons in 3 dimensions

Researchers at the Institute of Quantum Optics and Quantum Information, the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were able to entangle three ...

New evidence for the vibration theory of smell

(Âé¶¹ÒùÔº)—The predictive power and galvanizing influence that theoretical models routinely enjoy in physics is only rarely replicated in biology. Lord Raleigh's theory of sound perception, Francis Crick's sequence and ...

Superconductors could detect superlight dark matter

(Âé¶¹ÒùÔº)—Many experiments are currently searching for dark matter—the invisible substance that scientists know exists only from its gravitational effect on stars, galaxies, and other objects made of ordinary matter. ...

Mechanical quanta see the light

Interconnecting different quantum systems is important for future quantum computing architectures, but has proven difficult to achieve. Researchers from the TU Delft and the University of Vienna have now realized a first ...

Âé¶¹ÒùÔºicists posit quantum gravity's rainbow

When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theorists from the faculty of physics, University of Warsaw have shown that in models of the universe using any of ...

Short electron pulses make it possible to observe a structural change in a complex molecule as if watching a film

Chemistry is now ready for the movies: an international team which includes researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg has used a type of molecular camera to follow a fast-moving ...

Controlling the thermodynamics of light

The concept of temperature is critical in describing many physical phenomena, such as the transition from one phase of matter to another. Turn the temperature knob and interesting things can happen. But other knobs might ...

A quantum of light for materials science

Computer simulations that predict the light-induced change in the physical and chemical properties of complex systems, molecules, nanostructures and solids usually ignore the quantum nature of light. Scientists of the Max-Planck ...

Will we have to rewrite Einstein's theory of general relativity?

Einstein famously laboured hard to create the theory of general relativity, but it is less well known that he also helped to launch quantum mechanics, which he didn't much care for. These two views of the world are the very ...
