Kagome Superconductor Defies Time Reversal at Extreme Cold
Researchers at the Paul Scherrer Institute in Switzerland have achieved a breakthrough with the Kagome superconductor RbV3Sb5, which breaks time-reversal symmetry (TRS) at a record high temperature of 175 Kelvin (-144.67 °F). This development is significant for quantum systems, as TRS breaking at higher temperatures could lead to more practical and energy-efficient quantum technologies. The tunability of TRS breaking in RbV3Sb5, depending on the material's depth, offers potential for controlling quantum properties, paving the way for advancements in quantum device performance.
