Efficient fluctuation exchange approach to low-temperature spin fluctuations and superconductivity: from the Hubbard model to NaCoOHO
Niklas Witt, Erik G. C. P. van Loon, Takuya Nomoto +2
Superconductivity arises mostly at energy and temperature scales that are much smaller than the typical bare electronic energies. Since the computational effort of diagrammatic man…
Second-order dual fermion for multi-orbital systems
Erik G. C. P. van Loon
In dynamical mean-field theory, the correlations between electrons are assumed to be purely local. The dual fermion approach provides a systematic way of adding non-local correctio…
Coulomb Engineering of two-dimensional Mott materials
Erik G. C. P. van Loon, Malte Schüler, Daniel Springer +3
Two-dimensional materials can be strongly influenced by their surroundings. A dielectric environment screens and reduces the Coulomb interaction between electrons in the two-dimens…
