Proximity to understanding the cuprates
Scanning tunneling microscopy experiments in a high-temperature superconductor probe the temperature evolution of local electronic states, revealing that regions in the sample exhibiting weak superconductivity can persist to elevated temperatures if they are surrounded by regions of strong superconductivity.

A Tale of Two Domes
Iron selenide films peppered with potassium atoms exhibit a high-temperature superconducting phase that emerges separately from a low-temperature superconducting phase. Read More »
