Group theory of Wannier functions providing the basis for a deeper understanding of magnetism and superconductivity (Q2406225)

The paper under review deals with the group theory of best localized and symmetry-adapted Wannier functions in a crystal of any given space group or magnetic group. The analysis developed is restricted to Wannier functions that define magnetic or superconducting bands. That means that only Wannier functions centered at the atomic positions are considered. On the basis of the symmetry of the Wannier functions, this model of strongly correlated localized electrons makes clear predictions whether or not the system can possess superconducting or magnetic eigenstates. The paper is written in such a way that it should be possible to create a computer program automating the determination of Wannier functions.
