Slave-boson Formalism for Superconducting Pairing at Strong Coupling
Sarbajit Mazumdar, Jonas Issing, Jannis Seufert +4
We study the emergence of superconductivity in the one-band Hubbard model using the spin-rotation-invariant Kotliar-Ruckenstein slave-boson (SB) approach. Motivated by its intrinsi…
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…
Fluctuation corrections to the free energy of strongly correlated electron systems
David Riegler, Jannis Seufert, Ronny Thomale +1
We determine the free energy of strongly correlated electron systems in the example of the Hubbard model by calculating the contribution of spin and charge fluctuations to the Gutz…
Altermagnetic phase transition in a Lieb metal
Matteo Dürrnagel, Hendrik Hohmann, Atanu Maity +4
We analyze the phase transition between a symmetric metallic parent state and itinerant altermagnetic order. The underlying mechanism we reveal in our microscopic model of electron…
Incommensurate magnetic order: A fingerprint for electronic correlations in hole-doped cuprates
Michael Klett, Jacob Beyer, David Riegler +4
Intertwined charge and magnetic fluctuations in high- copper oxide superconductors (cuprates) are hypothesized to be a consequence of their correlated electronic nature…
Interplay of spin and charge order in the electron-doped cuprates
David Riegler, Jannis Seufert, Eduardo H. da Silva Neto +3
We study magnetic and charge order in the electron-doped high- cuprates based on the one-band Hubbard model with onsite () and nearest-neighbor interactions. To inves…
Maple Leaf Antiferromagnet in a Magnetic Field
Pratyay Ghosh, Jannis Seufert, Tobias Müller +2
We analyze the quantum antiferromagnet on the maple leaf lattice in the presence of a magnetic field. Starting from its exact dimer ground state and for a magnetic field strength o…
