In a one-dimensional chain of particles with an interaction based on the golden ratio, structures with crystalline order but without periodicity spontaneously emerge. A quasi-supersolid phase has been discovered: it holds its shape like ice and flows without friction. Experiments with cold atoms wil

A tiny crystal doped with europium acts like a mailbox for light: it captures pulses and stores them with almost no loss. Efficiency reached 80% for laser flashes and 70% for single photons. The device holds up to 20 light patterns at once, bringing quantum internet closer.
