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…

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…

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…
