Ultracold disappearing act: 'Matter waves' move through one another but never share space

Posted: 02 Nov 2014 01:01 PM PST

How can two clumps of matter pass through each other without sharing space? Physicists have documented a strange disappearing act by colliding Bose Einstein condensates that appear to keep their distance even as they pass through one another.

Step toward quantum computers: Two photons strongly coupled by glass fiber

Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists have now created the strongest possible coupling of only two photons -- an important achievement for quantum optics.

Scientists replicate the tide with two buckets, aquarium tubing, and a pump

A design for a new, inexpensive tidal simulation unit enables researchers to investigate tidal marsh plant growth in a controlled setting. The unit costs less than US$27 to build, takes up less than two square feet of space, and does not require external plumbing; the protocol is now available. The system could be an important tool for researchers working to preserve and restore environmentally important wetlands.
