Spin-Driven Nematic Instability of the Multi-Orbital Hubbard Model: Application to Iron-Based Superconductors
M. H. Christensen, Jian Kang, B. M. Andersen +1
Nematic order resulting from the partial melting of density-waves has been proposed as the mechanism to explain nematicity in iron-based superconductors. An outstanding question, h…
Self-Organized Topological Superconductivity in a Yu-Shiba-Rusinov Chain
M. Schecter, K. Flensberg, M. H. Christensen +2
We study a chain of magnetic moments exchange coupled to a conventional three dimensional superconductor. In the normal state the chain orders into a collinear configuration, while…
Spin reorientation driven by the interplay between spin-orbit coupling and Hund's rule coupling in iron pnictides
M. H. Christensen, Jian Kang, B. M. Andersen +2
In most magnetically-ordered iron pnictides, the magnetic moments lie in the FeAs planes, parallel to the modulation direction of the spin stripes. However, recent experiments in h…
