Unconventional superconductivity in Fe-based materials under extreme conditions

The discovery of superconductivity in Fe-based materials roughly ten years ago initiated a huge effort in the solid-state community to understand these fascinating solids. This symposium will address key issues in the Fe-based materials such as electronic nematicity, strong correlations due to Hund’s coupling, vestigial and intertwined phases, and the symmetry of the superconducting gap. Contributions both from experimental and theoretical viewpoints are welcome. A special emphasis will be placed upon tuning these systems with hydrostatic, as well as uniaxial, pressure.


Topics to be covered by the symposium:

 - Pressure effects in Fe-based materials (especially FeSe)
 - Uniaxial pressure (strain) effects (in particular in relation to electronic nematicity)
 - Strong electronic correlations due to Hund’s coupling
 - Vestigial and intertwined phases (double-Q etc.)
