2. Possibility of room temperature superconductivity. It is well known that the superconducting state is characterized by a quantum macroscopic state that arises from a Bose-Einstein condensation (BEC) of paired electrons (Cooper pairs). Initially, it is convenient to clarify some concepts regarding BEC.
Dream about room temperature superconductivity (RTS) was envisioned shortly after the discovery made by H. Kamerlingh-Onnes in 1911.

Superconductivity, discovered in 1911 and first theoretically understood in 1957, remains a fascinating phenomenon for reasons both fundamental and applied. Reliably calculating the critical temperature of a given material, and even more so predicting it, turned out to be a considerable challenge. This Colloquium explains how theoretical …
The dream of attaining room-temperature superconductivity (RTS) was born shortly after the discovery of the phenomenon in 1911. Recently, this goal has become perfectly realistic. It is important that the discovery of the high- T c oxides [ 1] did transfer the field of superconductivity to an entirely different energy scale.
