Superconductivity of elements

Elements have played an essential role in the study of superconductivity, helping us understand this phenomenon. Over the past decade, the progress of experimental and theoretical studies has been significant. The periodic table of superconducting elements added two new superconductors (Rb and Yb). An expanded pressure range of exploration achieved a substantial increase in the highest reported superconducting transition temperatures. Furthermore, we have observed a new direction in searching for novel superconducting phases by examining various temperature-pressure paths on energy landscapes. This paper reviews the state of the art in the superconducting properties of elements, highlighting the knowledge gained to enhance superconducting transition temperatures.
