The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

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 …

In the last decade, there has been a proliferation of laser sources for time-and angle-
resolved photoemission spectroscopy (TR-ARPES), building on the proven capability of this …

The combination of spin-orbit coupling with interactions results in many exotic phases of
matter. In this Letter, we investigate the superconducting pairing instability of the two …

Centrosymmetric materials with spin-degenerate bands are generally considered to be
trivial for spintronics and related physics. In two-dimensional (2D) materials with multiple …

The momentum dependence of the nematic order parameter is an important ingredient in
the microscopic description of iron-based high-temperature superconductors. While recent …

We have developed the numerical software package chinook for the simulation of
photoemission matrix elements. This quantity encodes a depth of information regarding the …

The role of nematic order for the mechanism of high-temperature superconductivity is highly
debated. In most iron-based superconductors (IBSs) the tetragonal symmetry is broken …

The importance of the spin-orbit coupling (SOC) effect in Fe-based superconductors
(FeSCs) has recently been under hot debate. Considering the Hund's coupling-induced …

In the superconducting regime of FeTe (1− x) Se x, there exist two types of vortices which are
distinguished by the presence or absence of zero-energy states in their core. To understand …
