Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the ...

is one of the world’s leading institutions and has so far realized an impressive range of different optical clocks - including optical single ion clocks and optical lattice clocks. The high level of ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

Without Katori's custom-made timekeeper, the experiment wouldn't have been possible, as conventional optical lattice clocks are so mammoth in size that just one can fill an entire laboratory.

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. Their study not only identifies the constraints of conventional sampling ...

Researchers developed a numerical simulation technique for light wave interactions in triangular-lattice PCSELs, enhancing ...

To address this challenge, the research team first trapped 173 Yb atoms with a spin of 5/2 in an optical lattice. By controlling laser pulses to induce nonlinear light shifts in the ground states ...
