Fermion-boson vertex within Dynamical Mean-Field Theory
Erik G. C. P. van Loon, Friedrich Krien, Hartmut Hafermann +2
In the study of strongly interacting systems, correlations on the two-particle level are receiving more and more attention. In this work, we study a particular two-particle correla…
Second-order dual fermion approach to the Mott transition in the two-dimensional Hubbard model
Erik G. C. P. van Loon, Mikhail I. Katsnelson, Hartmut Hafermann
We apply the dual fermion approach with a second-order approximation to the self-energy to the Mott transition in the two-dimensional Hubbard model. The approximation captures nonl…
Confining graphene plasmons to the ultimate limit
Alessandro Principi, Erik van Loon, Marco Polini +1
Graphene plasmons have recently attracted a great deal of attention because of their tunability, long lifetime, and high degree of field confinement in the vertical direction. Near…
