Dynamical vortices in electron-phonon superconductors
Morten H. Christensen, Andrey V. Chubukov
We analyze the structure of an wave superconducting gap in systems with electron-phonon attraction and electron-electron repulsion. Earlier works have found that superconductiv…
Theory of the charge-density wave in VSb kagome metals
Morten H. Christensen, Turan Birol, Brian M. Andersen +1
The family of metallic kagome compounds VSb (=K, Rb, Cs) was recently discovered to exhibit both superconductivity and charge order. The nature of the charge-density…
Strong-coupling expansion of multi-band interacting models: mapping onto the transverse-field - Ising model
Xiaoyu Wang, Morten. H. Christensen, Erez Berg +1
We investigate a class of two-dimensional two-band microscopic models in which the inter-band repulsive interactions play the dominant role. We first demonstrate three different sc…
Prediction of Double-Weyl Points in the Iron-Based Superconductor CaKFeAs
N. Heinsdorf, M. H. Christensen, M. Iraola +6
Employing a combination of symmetry analysis, low-energy modeling, and ab initio simulations, we predict the presence of magnetic-field-induced Weyl points close to the Fermi level…
