Emergent electronic phenomena in iron-based superconductors have been at the forefront
of condensed matter physics for more than a decade. Much has been learned about the …

Iron-based superconductors are well known for their complex interplay between structure,
magnetism and superconductivity. FeSe offers a particularly fascinating example. This …

Almost a decade has passed since the serendipitous discovery of the iron-based high
temperature superconductors (FeSCs) in 2008. The fact that, as in the copper oxide high …

We propose an SU (4) spin-valley-fermion model to investigate the superconducting
instabilities of twisted bilayer graphene (TBG). In this approach, bosonic fluctuations …

BaNi2As2 is a structural analog of the pnictide superconductor BaFe2As2, which, like the
iron-based superconductors, hosts a variety of ordered phases including charge density …

The electronic nematic phase—in which electronic degrees of freedom lower the crystal
rotational symmetry—is commonly observed in high-temperature superconductors …

Nematic phases, in which electrons in a solid spontaneously break rotational symmetry
while preserving translational symmetry, exist in several families of unconventional …

Spin–orbit coupling (SOC) is a fundamental physical interaction, which describes how the
electrons' spin couples to their orbital motion. It is the source of a vast variety of fascinating …

Monolayer FeSe exhibits the highest transition temperature among the iron based
superconductors and appears to be fully gapped, seemingly consistent with s-wave …

We formulate the superfluid weight in unconventional superconductors with k-dependent
Cooper pair potentials based on the geometric properties of Bloch electrons. We apply the …
