Abstract

Superconductors and superfluids, have ever since their discovery, been of great academic interest in physics. This is reflected by the fact that eighteen people have been awarded Nobel prizes for studying such systems during the last century. A remarkable aspect is that the microworld laws appear in these highly coherent states as collective phenomena with manifestations on macroscopic length scales. For this reason, research on superconductors and superfluids has generated concepts that are also useful in ostensibly unrelated branches of physics. Besides the fundamental interest in these states, there is a growing list of their existing and potential applications. These range from MRI, power lines, and current controllers, to high precision gyroscopes and accelerometers and most recently a pursuit has started to use these states for implementation of qubits for quantum computers and quantum emulators. In recent years there was a number of experimental breakthroughs in condensed matter systems which exhibit multi-component many-body degrees of freedom, making it rich emergent research field. As a consequence of having several type of carriers responsive for superconductivity, these materials behave fundamentally different from traditional superconductors. This superconducting state requires theoretical understanding from the fundamental viewpoint and also in order to use such materials in practical applications. which we plan to address in the project.
