As we know, the symmetry of the electronic charge distribution in solids closely follows that of the crystal lattice. Depending on temperature or other factors this symmetry can be broken as a result of self-organisation of the valence electrons. Examples include superconductivity, density waves, orbital ordering, quantum magnetism or colossal magneto-resistance. A central challenge in modern condensed matter physics is to understand such many-body systems and identify the strong interactions which lead to these ordering phenomena.
The most concise and informative characteristic of the electronic order and its symmetry is the Fermi surface, a surface in reciprocal space confining the occupied electronic states. The notion of the Fermi surface developed in quantum physics made it possible to explain many physical properties of metals: their ability to conduct electric current and heat, their ductility, shininess etc. Detailed understanding of the Fermi surface and supporting low-energy electronic structure of the systems exhibiting different ordering phenomena will certainly help to unravel the underlying mechanisms of quantum electronic order and show the roots to synthesis of functional materials with desired physical properties.
Novel experimental methods, such as angle-resolved photoemission spectroscopy, offer a direct access to the Fermi surface and low-energy electronic structure of solids. On the other hand, the Fermi surface and electronic dispersion can also be calculated from the first principles. Using both tools, it became possible to characterize what is required most for complete understanding of particular type of the quantum electronic order - the symmetry and strength of the interactions which finally define the physical properties in those systems.
Contributions are invited on both experimental and theoretical studies of low-energy electronic structure of solids with emphasis on the Fermi surface. Possible classes of materials include, but not limited to:
- spin density waves compounds,
- charge density waves compounds,
- orbitally ordered systems,
- topological insulators,
- carbon-based materials,
