Flow without friction is a strange phenomenon usually seen in quantum fluids that are cooled to temperatures near absolute zero, but features of superfluidity have now been seen with polaritons at ambient conditions.
INSPIRE, the central information resource of the high-energy physics community, pioneered the open dissemination of scientific literature. It has been evolving to keep up with the new technologies and it is not slowing down.
Some Springer Nature journals, including Nature Physics, are mandating Open Researcher and Contributor IDs (ORCIDs) for the corresponding authors of accepted papers. We provide some context to this initiative.
An excitonic Bose–Einstein condensate has so far been realized only in particular semiconductor heterostructure setups. Now, experiments show that such condensates can form in double graphene bilayers separated by hexagonal boron nitride.
