Two stopped light pulses interact with each other
(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the ...
Vertical cavity quantum switch could lead us away from electronics-based computing
(PhysOrg.com) -- Right now, many researchers around the world are working on ways to move away from electronics-dominated computing systems. There are a number of ideas about how this can be accomplished. "We are trying to ...
Oil-based color pixels could let you watch videos on e-paper
(PhysOrg.com) -- By rapidly manipulating colored oil droplets stacked on top of each other, a new electrowetting (EW) technique could lead to the development of electronic paper displays that can produce high-resolution ...
Shocking: Environmental chemistry affects ferroelectric film polarity the same way electric voltage does
(PhysOrg.com) -- “Ferroelectric materials are interesting scientifically, and, while they are used for some things now, they are potentially useful for even more applications in the future,” Brian Stephenson tells PhysOrg.com. Stephe ...
Reversible doping: Hydrogen flips switch on vanadium oxide
If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks ...

Engineers at Yale develop new type of mechanical memory
(PhysOrg.com) -- Research engineers at Yale University have succeeded in building a mechanical memory switch that is controlled and then read by lasers. In their paper published in Nature Nanotechnology, the te ...
Single molecule can shift the phase of a laser beam
(PhysOrg.com) -- The ability to control light forms the basis of many technologies, from microscopy to optical computing. Now, a team of scientists from ETH in Zurich, Switzerland, has demonstrated that a ...
Before animals first walked on land, fish carried gene program for limbs
