Building blocks of topological band theory for photonic crystals
Yoonseok Hwang, Vaibhav Gupta, Antonio Morales-Pérez +6
We derive a framework for classifying topological bands in three-dimensional photonic band structures, where the zero frequency polarization singularity implied by Maxwell's equati…
Symmetry-breaking-induced topology in FeSe
Mikel García-Díez, Jonas B. Profe, Augustin Davignon +3
FeSe has been one of the most intensively studied iron-based superconductors over the past two decades, exhibiting a wide range of phenomena such as unconventional superconductivit…
Flat band driven itinerant magnetism in the Co-pnictides CaCoAs and LaCoP
D. Subires, M. García-Díez, A. Kar +12
Flat bands can induce strong electron correlation effects that help stabilize both magnetic and superconducting states. Here, we carry out angle-resolved photoemission spectroscopy…
Origins of the anomalous Hall conductivity in the symmetry enforced Fe3GeTe2 nodal-line ferromagnet
Mikel García-Díez, Haim Beidenkopf, Iñigo Robredo +1
FeGeTe has gained attention in the condensed matter community for its potential to be exfoliated into thin films with ferromagnetic (FM) order, thanks to its van der Waals…
Band representations in Strongly Correlated Settings: The Kitaev Honeycomb Model
Axel Fünfhaus, Mikel García-Díez, M. G. Vergniory +3
In the study of quantum spin liquids, the Kitaev model plays a pivotal role due to the fact that its ground state is exactly known as well as the fact that it may be realized in st…
