Superconduction: Why does it have to be so cold?

Currently, there is no precise computation method to describe superconducting materials. TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around -200°C - Why does it always have to be so cold? We now know of a whole range of materials that ' under certain conditions ' conduct electrical current entirely without resistance. We call this phenomenon superconduction. All these materials do nonetheless experience a common problem: they only become superconducting at extremely low temperatures. The search to find theoretical computational methods to represent and understand this fact has been going on for many years. As yet, no one has fully succeeded in finding the solution. However, TU Wien has now developed a new method that enables a significantly better understanding of superconduction.
