Scientists have proposed a new system for time, the principle of which is based on neutrons in the atomic nucleus. They will also have unprecedented precision, without gaining or losing even 1/20 of a second for 14 billion years, which is the age of the universe.
"This is almost 100 times more accurate than the best atomic clock," - said one of the researchers, Professor Victor Flambaum, who heads the department of theoretical physics.
"This will not only allow researchers to test the fundamental theories of physics at an unprecedented level of accuracy, but will be unparalleled tool for research in the field of applied physics."
In their research article to be published in the journal Physical Review Letters, the scientists Flabaum and Vladimir Dziuba, reported that the accuracy of their proposed ionic hours will go up to 19 numbers after the decimal point.
The range of application is incredibly accurate atomic clocks varies, ranging from GPS-navigation systems and broadband data to test in the field of fundamental physics and system synchronization in particle accelerators.
"As today’s atomic clocks at the moment is close to the threshold of its accuracy, the next generation of systems should have extreme precision, which will expand the scope of their application to new limits, for the moment remain beyond the capabilities of an atomic clock," - said Professor Flabaum.
"Atomic clocks use the electrons orbiting the nucleus of an atom as a kind of pendulum clock. But we have demonstrated that using lasers for the location of the electrons in a special way, you can make the neutrons of the atomic nucleus to function as such a pendulum, which will create the atomic clock of unprecedented accuracy."
Since the neutron is firmly seated in the nucleus, it practically does not affect any external changes, in contrast to the electrons of atomic clocks, which are more easily influenced.
