Near ground-state cooling of 2-D trapped ion crystals

Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...

Nanomagnets levitate thanks to quantum physics

Quantum physicists in Oriol Romero-Isart's research group in Innsbruck show in two current publications that, despite Earnshaw's theorem, nanomagnets can be stably levitated in an external static magnetic field owing to quantum ...

Detecting radio waves with entangled atoms

In a study published in Physics Review Letters and highlighted by APS Physics, ICFO researchers demonstrate a new technique for the coherent detection of radio frequency magnetic fields using an atomic magnetometer. They ...

Creating time crystals with a rotating ion ring

(Phys.org) —There has been a lot of talk recently about the possibility of building what has come to be known as a time crystal. In February 2012, Frank Wilczek originally proposed the idea that under certain conditions, ...
