Competing magnetic fluctuations and orders in a multiorbital model of doped SrCoAs
Ana-Marija Nedić, Morten H. Christensen, Y. Lee +6
We revisit the intriguing magnetic behavior of the paradigmatic itinerant frustrated magnet , which shows strong and competing magnetic fluctuations yet…
Loop currents in VSb kagome metals: multipolar and toroidal magnetic orders
Morten H. Christensen, Turan Birol, Brian M. Andersen +1
Experiments in the recently discovered vanadium-based kagome metals have suggested that their charge-ordered state displays not only bond distortions, characteristic of a ``real" c…
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…
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…
Laser-induced coherent control of an electronic nematic quantum phase transition
Avraham Klein, Morten H. Christensen, Rafael M. Fernandes
Ultrafast techniques have emerged as promising methods to study and control quantum materials. To maintain the quantum nature of the systems under study, excess heating must be avo…
