Time crystals represent a new phase of matter proposed by Frank Wilczek, the Nobel laureate of Physics in 2004; they can break original time-translation symmetry and create new time oscillations ...

One of the most vital pieces of equipment housed at the Space Science Center is the University's hydrogen maser. Given to the center in 2016 by MIT, the device uses hydrogen gas to determine an atomic ...

But nobody has ever spotted an atomic hydrogen cloud with an associated maser, and that's what would be needed to explain the intensity of the Wow! signal. That's why other astronomers are opting ...

It's why the world's timekeepers add leap seconds every so often. Getty Images An early atomic clock "maser", in the mid-1950s (Credit: Getty Images) The hydrogen masers at NPL in London are some ...

A maser is a device for emitting a coherent beam of microwaves, used in particular to obtain the reference frequency for atomic clocks. It works in a similar way to the passive masers used on ...

With each cycle, a maser—like a laser that produces microwaves ... nine gigahertz—is used to calibrate about 18 smaller atomic clocks at NIST that run 24 hours a day. Housed in egg incubators ...

Such factors are bolstering the atomic clock market size. With the increasing number of consumers, telecommunication network providers require highly precise clocks for digital signals to be ...

Atomic clocks keep time far more accurately ... Back at NPL, as I read the "do not touch the maser" sign, I ask one of the scientists showing me around if he himself is a good timekeeper: is ...
