Physicists coax molecules into exotic quantum state — ending decades-long quest

Posted by in categories: materials, quantum physics

The results are “fantastic”, says Yan. They will “really inspire and stimulate the rest of the cold-molecules community”

Exotic phases

Molecular Bose–Einstein condensates could be used in myriad ways. One possibility, says Valtolina, is to create exotic supersolid phases, in which a rigid material flows without resistance. So far this has been achieved only in atomic gases with magnetic interactions — it could now be done in polar molecules, whose interactions are “way stronger”, he says.

Scientists bring crystal clarity to diamond’s quantum signals

Posted by in category: quantum physics

They say that one can miss the forest for the trees. But it’s often worth taking a closer look at the trees to make sense of the dense, brambly whole. That’s what a Stanford University group did to tackle a thorny quantum-information problem in diamond.

Chemists uncover reversible assembly of platinum nanocatalyst

Posted by in categories: nanotechnology, particle physics

Chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Stony Brook University (SBU), and their collaborators have uncovered new details of the reversible assembly and disassembly of a platinum catalyst. The new understanding may offer clues to the catalyst’s stability and recyclability.

The work, described in a paper published in the journal Nanoscale (“Unravelling the origin of reaction-driven aggregation and fragmentation of atomically dispersed Pt catalyst on ceria support”), reveals how single platinum atoms on a cerium oxide support aggregate under reaction conditions to form active catalytic nanoparticles — and then, surprisingly, fragment once the reaction is stopped.

Fragmentation may sound shattering, but the scientists say it could be a plus.
