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…
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…
Evolution of nematic fluctuations in CaK(FeNi)As with spin-vortex crystal magnetic order
Anna E. Böhmer, Fei Chen, William R. Meier +11
The CaK(FeNi)As superconductors resemble the archetypal 122-type iron-based materials but have a crystal structure with distinctly lower symmetry. This fa…
Modeling unconventional superconductivity at the crossover between strong and weak electronic interactions
Morten H. Christensen, Xiaoyu Wang, Yoni Schattner +2
High-temperature superconductivity emerges in a host of different quantum materials, often in a region of the phase diagram where the electronic kinetic energy is comparable in mag…
Evidence for a pressure-induced antiferromagnetic quantum critical point in intermediate valence UTe2
S. M. Thomas, F. B. Santos, M. H. Christensen +7
UTe is a recently discovered unconventional superconductor that has attracted much interest due to its many intriguing properties - a large residual density-of-states in the su…
