Altermagnons at the metal-insulator transition
Jonas Issing, Matteo Dürrnagel, Sarbajit Mazumdar +7
By means of slave-boson theory for the Hubbard model on the checkerboard lattice, we calculate dynamical altermagnetic spin susceptibilities from the metallic to the Mott-insulatin…
Topologically enabled superconductivity: possible implications for rhombohedral graphene
Francesca Paoletti, Daniele Guerci, Giorgio Sangiovanni +2
We present a topological mechanism for superconductivity emerging from Chern-2 insulators. While, naively, time-reversal symmetry breaking is expected to prevent superconductivity,…
Electrical Transport in the Hatsugai-Kohmoto Model
Daniele Guerci, Giorgio Sangiovanni, Andrew J. Millis +1
We show that in models with the Hatsugai-Kohmoto type of interaction that is local in momentum space thus infinite-range in real space, Kubo formulas neither reproduce the correct…
Interconnected Renormalization of Hubbard Bands and Green's Function Zeros in Mott Insulators Induced by Strong Magnetic Fluctuations
Evgeny A. Stepanov, Maria Chatzieleftheriou, Niklas Wagner +1
We analyze the role of spatial electronic correlations and, in particular, of the magnetic fluctuations in Mott insulators. A half-filled Hubbard model is solved at large strength…
Tomographic Imaging of Orbital Vortex Lines in Three-Dimensional Momentum Space
T. Figgemeier, M. Ünzelmann, P. Eck +16
We report the experimental discovery of orbital vortex lines in the three-dimensional (3D) band structure of a topological semimetal. Combining linear and circular dichroism in sof…
Edge zeros and boundary spinons in topological Mott insulators
Niklas Wagner, Daniele Guerci, Andrew J. Millis +1
We introduce a real-space slave rotor theory of the physics of topological Mott insulators, using the Kane-Mele-Hubbard model as an example, and use it to show that a topological g…
