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…
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…
From high- to low-: Multi-orbital effects in transition metal oxides
Michael Klett, Tilman Schwemmer, Sebastian Wolf +8
Despite the structural resemblance of certain cuprate and nickelate parent compounds there is a striking spread of among such transition metal oxide superconductors. We adopt…
Slave-Boson analysis of the 2D Hubbard model
David Riegler, Michael Klett, Titus Neupert +2
We present a comprehensive study of the 2D one-band Hubbard model applying the spin rotation invariant slave-boson method. We utilize a spiral magnetic mean field and fluctuations…
