Two-particle correlations and the metal-insulator transition: Iterated Perturbation Theory revisited
Erik G. C. P. van Loon
Recent advances in many-body physics have made it possible to study correlated electron systems at the two-particle level. In Dynamical Mean-Field theory, it has been shown that th…
Local Plaquette Physics as Key Ingredient of High-Temperature Superconductivity in Cuprates
M. Danilov, E. G. C. P. van Loon, S. Brener +3
A major pathway towards understanding complex systems is given by exactly solvable reference systems that contain the essential physics of the system. For the Hubbard mode…
Random Phase Approximation for gapped systems: role of vertex corrections and applicability of the constrained random phase approximation
Erik G. C. P. van Loon, Malte Rösner, Mikhail I. Katsnelson +1
The many-body theory of interacting electrons poses an intrinsically difficult problem that requires simplifying assumptions. For the determination of electronic screening properti…
Downfolding approaches to electron-ion coupling: Constrained density-functional perturbation theory for molecules
Erik G. C. P. van Loon, Jan Berges, Tim O. Wehling
Constrained electronic-structure theories enable the construction of effective low-energy models consisting of partially dressed particles. However, the interpretation and physical…
A full gap above the Fermi level: the charge density wave of monolayer VS2
Camiel van Efferen, Jan Berges, Joshua Hall +15
In the standard model of charge density wave (CDW) transitions, the displacement along a single phonon mode lowers the total electronic energy by creating a gap at the Fermi level,…
