A new piece in the high-temperature superconductivity puzzle: 'Dressing' in superconductors

The physical mechanism that generates superconductivity in materials at high critical temperature (like cuprates, which appear to be among the most promising materials for technological applications) remains a mystery. So far, experimental observations haven't clarified if the phenomenon at work in conventional superconductors -- at low critical temperature -- and involving the "dressing" concept (as physicists call it) can also be seen in cuprates, but one study, published in Nature Communications and coordinated by Elettra Sincrotrone of Trieste, the University of Trieste and the University of Naples Federico II (with the participation of SISSA) suggests that this might be the case.
