LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

Angle resolved photoemission spectroscopy (ARPES) reveals the features of the electronic
structure of quasi-two-dimensional crystals which are crucial for spin and charge ordering …

In the first three years since the discovery of Fe-based high T c superconductors, scanning
tunneling microscopy (STM) and spectroscopy have shed light on three important questions …

An ultrasharp photoluminescence line intimately related to antiferromagnetic order has been
found in NiPS 3, a correlated van der Waals material, opening prospects for magneto-optical …

New developments in the field of topological matter are often driven by materials discovery,
including novel topological insulators, Dirac semimetals, and Weyl semimetals. In the last …

In the novel stoichiometric iron-based material RbEuFe 4 As 4, superconductivity coexists
with a peculiar long-range magnetic order of Eu 4f states. Using angle-resolved …

Unfolding the band structure of a supercell to a normal cell enables us to investigate how
symmetry breakers such as surfaces and impurities perturb the band structure of the normal …

A fundamental part of the puzzle of unconventional superconductivity in the Fe-based
superconductors is the understanding of the magnetic and nematic instabilities of the parent …

We demonstrate the growth of Co-doped BaFe 2 As 2 (Ba-122) thin films on CaF 2 (001),
SrF 2 (001), and BaF 2 (001) single crystal substrates using pulsed laser deposition. All films …

We present a general method to unfold energy bands of supercell calculations to a primitive
Brillouin zone using group theoretical techniques, where an isomorphic factor group is …
