![]() In their new study, they created a multiplexed clock, where strontium atoms can be separated into multiple clocks arranged in a line in the same vacuum chamber. Designing a clock that could use average lasers would be a boon. But they also knew that many downstream applications of optical clocks will require portable, commercially available lasers like theirs. ![]() Optical atomic clocks keep time by using a laser that is tuned to precisely match this frequency, and they require some of the world's most sophisticated lasers to keep accurate time.īy comparison, Kolkowitz's group has "a relatively lousy laser," he says, so they knew that any clock they built would not be the most accurate or precise on its own. "We're working to both improve their performance and to develop emerging applications that are enabled by this improved performance."Ītomic clocks are so precise because they take advantage of a fundamental property of atoms: when an electron changes energy levels, it absorbs or emits light with a frequency that is identical for all atoms of a particular element. "Optical lattice clocks are already the best clocks in the world, and here we get this level of performance that no one has seen before," says Shimon Kolkowitz, a UW-Madison physics professor and senior author of the study. Its design allows the team to test ways to search for gravitational waves, attempt to detect dark matter, and discover new physics with clocks. It can be tweaked in terms of aesthetics, and can sit in plain sight to display accurate info you need.Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to losing just one second every 300 billion years and is the first example of a "multiplexed" optical clock, where six separate clocks can exist in the same environment. To sum it up, Atomic Clock is a simple little desktop gadget which allows you to stay updated with a preferred timezone. We have not come across any issues during our tests Atomic Clock did not cause Windows to freeze, crash or pop up error dialogs. The simplistic app puts little strain on the computer's CPU and system memory and has a good response time. Options provided by the operating system let you move Atomic Clock anywhere on the screen, make it stay on top of other applications and adjust its opacity level between 20% and 100%. background, local time, synchronize, error messages). In addition, you can disable sounds, enable update notifications, hide the title and copyright text, as well as customize colors for the interface (e.g. Tweak colors and soundįrom the 'Settings' area you can change the layout size and make the app get the time from the server at a custom interval, as well as change the time and date format. Atomic Clock can also guide you if you want to synchronize the local time with the server time. The interface of the tool is based on a small window where you can check out the local and service time and date, along with the difference between them. This way, you can store Atomic Clock on an external device (like a USB flash drive) and always have it with you when you're on the go. Thanks to its GADGET extension, the lightweight app does not require any installation. A gadget host application is first required Atomic Clock is a small gadget that connects to world time servers and shows you the difference between your system local time and the real time.
