Exotic Electronic Order in a Parabolic Kagome Semimetal
C. Alexander Baum, Jonas Issing, Sarbajit Mazumdar +4
We study an interacting kagome-lattice realization of a quadratic band-touching semimetal at 2/3 filling with onsite and nearest-neighbor repulsive interactions. Combining function…
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…
Engineering altermagnetic orders on the square-kagome lattice through sublattice interference
Jonas Issing, Jannis Seufert, Michael Klett +4
We investigate the emergence of altermagnetic (AM) phases on the square-kagome lattice. Our analysis reveals that matrix element effects due to an orthogonal sublattice weight deco…
