Just seven photons can act like billions

A system made of just a handful of particles acts just like larger systems, allowing scientists to study quantum behaviour more easily.

Chasing dark matter with the oldest stars in the Milky Way

Just how quickly is the dark matter near Earth zipping around? The speed of dark matter has far-reaching consequences for modern astrophysical research, but this fundamental property has eluded researchers for years.

Engineering electron pathways in 2-D topological insulators

In a recent article published in Physical Review Letters a research collaborative has reported new insights into the electronic conduction and interference on 2-D topological insulators—an exotic kind of insulator that ...

We are lucky to live in a universe made for us

To a human, the universe might seem like a very inhospitable place. In the vacuum of space, you would rapidly suffocate, while on the surface of a star you would be burnt to a crisp. As far as we know, all life is confined ...

Revealed: Positronium's behavior in particle billiards

Collision physics can be like a game of billiards. Yet in the microscopic world, the outcome of the game is hard to predict. Fire a particle at a group of other particles, and they may scatter, combine or break apart, according ...

Physicists investigate onset of effective mass

(Phys.org) —Although mass may seem to be a fairly straightforward concept, from a physics perspective it can be much more complex than weighing an object and reading off a number in grams. For instance, an object's mass ...

New study reveals insights on plate tectonics

(Phys.org) —The Earth's outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought to understand ...
