Proximitizing altermagnets with conventional superconductors
Niclas Heinsdorf, Marcel Franz
Recent theoretical work highlighted unique properties of superconducting altermagnets, including the wealth of topologically non-trivial phases as well as their potential uses in s…
Persistent spin currents in superconducting altermagnets
Kyle Monkman, Joan Weng, Niclas Heinsdorf +2
Superconductors are famously capable of supporting persistent electrical currents, that is, currents that flow without any measurable decay as long as the material is kept in the s…
Correlated insulating states in slow Dirac fermions on a honeycomb moir{é} superlattice
Dongyang Yang, Jing Liang, Haodong Hu +8
Strong Coulomb repulsion is predicted to open a many-body charge gap at the Dirac point of graphene, transforming the semimetal into a Mott insulator. However, this correlated insu…
Comment on: "Dynamics of disordered quantum systems with two- and three-dimensional tensor networks" arXiv:2503.05693
Andrew D. King, Alberto Nocera, Marek M. Rams +8
In a recent preprint [1] (arXiv:2503.05693), Tindall et al. presented impressive classical simulations of quantum dynamics using tensor networks. Their methods represent a signific…
Altermagnetism in modified Lieb lattice Hubbard model
Nitin Kaushal, Marcel Franz
We study the emergence of altermagnetism from repulsive interactions for electrons on the Lieb lattice as a model of quasi-2D oxychalcogenides with the so-called "anti-CuO" l…
