New exotic two-dimensional Superconducting state of matter found

1 min read

One Indian origin scientist and other scientists have found the sign of a new and exotic matter state where the component particles pair up when limited to two dimensions. This finding is issued in the journal Science which includes significant signs of the new phenomenon of superconductivity.

This theory of exactly zero electrical resistance and expulsion of magnetic flux fields appearing in specific materials is known as superconductors when cooled below than a critical temperature.

Superconductivity is a mechanical phenomenon which is described by the Meissner effect. The full expulsion of magnetic field lines from the interior of the superconductor as it transitions into the superconducting state. It is the most relevant class of material with especially critical temperature for superconductivity. There is evidence that for the superconductivity to occur, a particular type of particles, i.e. fermions must pair up.

A PhD student at Heidelberg University Puneet Murthy said that in solid-state materials like copper oxides many different properties and impurities make these elements hard to study. That is why scientists use ultracold atoms to simulate the behaviour of electrons in solids. This enables to create very clean samples and gives us full control over the essential system parameters.
