Researchers are exploring multi-level atomic interactions to enhance quantum entanglement. Using metastable states in strontium, they demonstrate how photon exchange can sustain correlations, offering ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

Ultracold fermions in optical lattices represent a fascinating area of research in condensed matter physics, where scientists explore the behavior of fermionic particles at temperatures close to ...

A research team from Skoltech and ITMO university has obtained tunable polariton emission at room temperature on CsPbBr3 ...

In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...

The research created a two-dimensional non-Hermitian topological band for ultracold fermions in spin-orbit-coupled optical lattices with tunable dissipation, unveiling the non-Hermitian skin ...

Recent research published in Physical Review Letters by PTB (Physikalisch-Technische Bundesanstalt) details the development ...

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.
