Physicists 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 ...

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 ...

May the fifth force be with you

Discovering possible new forces in nature is no mean task. The discovery of gravity linked to Newton's arguably apocryphal apple experiment has remained anchored in popular culture. In January 1986, Ephraim Fischbach, Physics ...
