Abstract

Cuprates are superconducting materials that reach the highest known temperatures. The research carried out by Anaëlle Legros highlights a new fundamental feature of cuprates in their non-superconducting state: electrons dissipate their energy as quickly as possible to reach a quantum critical point related to the Planck constant. The work therefore reveals extremely strong interactions between electrons, leading to a better understanding of these wholly unique superconductors and the origin of their significant superconductivity. Being able to harness superconductivity at room temperature could give rise to tremendous technological impacts, including the option to transport and store electricity at no energy cost.
