In a groundbreaking discovery, researchers have found that certain disordered superconductors like indium oxide films experience sharp and sudden phase transitions. This revelation challenges conventional beliefs about how these transitions occur, with significant implications for the future of quantum computing technology.
The comprehensive study, published in the prestigious journal Nature, revealed that indium oxide films defy traditional expectations by shifting abruptly from a superconducting to an insulating state. This dramatic first-order transition is a stark contrast to the gradual, second-order transitions usually observed in superconductors.
Kulcsfontosságú kísérleti megállapítások: Researchers noted a drastic drop in superfluid stiffness — a pivotal factor in a material’s superconducting capability — at a critical level of disorder. This suggests that the critical temperature linked with superconductivity is not determined by electron pairing strength but rather by superfluid stiffness.
Such findings highlight the need to rethink traditional models of quantum phase transitions and open new avenues for research into the effects of disorder on superconductivity in various materials.
