Pseudogap at hot spots in the two-dimensional Hubbard model at weak coupling
Daniel Rohe, Walter Metzner
We analyze the interaction-induced renormalization of single-particle excitations in the two-dimensional Hubbard model at weak coupling using the Wick-ordered version of the functi…

Interaction flow method for many-fermion systems
Carsten Honerkamp, Daniel Rohe, Sabine Andergassen +1
We propose an interaction flow scheme that sums up the perturbation expansion of many-particle systems by successively increasing the interaction strength. It combines the unbiased…

Rescattering Contributions to Final State Interactions in (e,e'p) Reactions at High (p_m,E_m)
C. Barbieri, L. Lapikas
The contribution of rescattering to final state interactions in the (e,e'p) cross section is studied using a semiclassical model. This approach considers a two-step process with th…
