Quantum rings in the grip of laser light

Ultracold atoms trapped in appropriately prepared optical traps can arrange themselves in surprisingly complex, hitherto unobserved structures, according to scientists from the Institute of Nuclear Physics of the Polish Academy ...

A trap for positrons

For the first time, scientists from the Technical University of Munich (TUM) and the Max Planck Institute for Plasma Physics (IPP) have succeeded in losslessly guiding positrons, the antiparticles of electrons, into a magnetic ...

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 ...
