Is random lasing possible with a cold atom cloud?

(PhysOrg.com) -- Random lasing, Robin Kaiser tells PhysOrg.com, is like standard lasing, with a little bit of a twist: “You don’t know the direction the photons will go, as you do with a more standard laser. This is because ...

Nanotube-based terahertz polarizer nears perfection

(PhysOrg.com) -- Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication devices, sensors ...

Quantum cycles power cold-atom pump

The idea of a pump is at least as old as the ancient Greek philosopher and scientist Archimedes. More than 2000 years ago, Archimedes allegedly invented a corkscrew pump that could lift water up an incline with the turn of ...

Simulation of chiral edge states in a quantum system

Researchers in Florence and Innsbruck have simulated a physical phenomenon in an atomic quantum gas that can also be observed at the edge of some condensed matter systems: chiral currents. The scientists have published the ...

The 500 phases of matter: Entering a new phase

(Phys.org)—Forget solid, liquid, and gas: there are in fact more than 500 phases of matter. In a major paper in today's issue of Science, Perimeter Faculty member Xiao-Gang Wen reveals a modern reclassification of all of ...
