UChicago Scientists Build Trap to Make Tiny Packages of Light ‘Collide’

UChicago Scientists Build Trap to Make Tiny Packages of Light ‘Collide’

The universe is illuminated via photons, the tiny individual particles that make up light, but they don’t interact with each other. To make them see the light, a team of University of Chicago physicists built a trap to help photons bounce off each other.

Their photon collider, described in the March 19 edition of Nature Physics, is the latest effort to make photons behave like other particles…

Self-Assembling, Tunable Interfaces Found in Quantum Materials

Self-Assembling, Tunable Interfaces Found in Quantum Materials

A potential revolution in device engineering could be underway, thanks to the discovery of functional electronic interfaces in quantum materials that can self-assemble spontaneously.

“This illustrates that if we can learn to control and exploit the remarkable properties at the interfaces of quantum materials, this will likely result in a new generation of devices beyond our current imagination,”…

Epidemics: the End of Containment Measures?

When an epidemic outbreak – such as those caused by the H1N1, Zika or SARS viruses – takes place, containment measures may seem to be the most reasonable solution. However, an EPFL study casts doubt on that idea, showing that such measures make a society less resilient and less able to quickly return to their pre-epidemic economic and social situation.

The study, published in Nature Scientific…

X-Ray Experiments Suggest High Tunability of 2-D Material

To see what is driving the exotic behavior in some atomically thin – or 2-D – materials, and find out what happens when they are stacked like Lego bricks in different combinations with other ultrathin materials, scientists want to observe their properties at the smallest possible scales.

Enter MAESTRO, a next-generation platform for X-ray experiments at the Advanced Light Source (ALS) at the…

Diffused Light shows Clear Structures

Diffused Light shows Clear Structures

Scientists gain an insight into the fascinating world of atoms and molecules using x-ray microscopes. Ground-breaking research by physicists at FAU, the Deutsches Elektronen Synchrotron (DESY) in Hamburg, and the University of Hamburg has paved the way towards new imaging techniques. The team of scientistshave successfully developed and tested a method which is considerably more effective than…

GENERAL INFO

KEY TOPICS

The current theory, known as the Standard Model of particle physics, has predicted some violation of matter-antimatter symmetry, but not enough to explain how our universe arose consisting mostly of matter with barely a trace of antimatter.(More…)

Light: can you feel the force?

Light: can you feel the force?

It is well established that light exerts a momentum in the direction of propagation, solar sail propulsion on a spacecraft being just one example of this effect.  Surprisingly, light can also carry linear momentum perpendicular to its propagation direction. This component originates from a field-theoryconstruction introduced by Dutch physicist Frederik Jozef Belinfante more than 70 years ago,…
