Exceptional points in the one-dimensional Hubbard model
Roman Rausch, Robert Peters, Tsuneya Yoshida
Non-Hermitian phenomena offer a novel approach to analyze and interpret spectra in the presence of interactions. Using the density-matrix renormalization group (DMRG), we demonstra…

Topological phases arising from attractive interaction and pair hopping in the Extended Hubbard Model
Roman Rausch, Matthias Peschke
The extended Hubbard model with an attractive density-density interaction, positive pair hopping, or both, is shown to host topological phases, with a doubly degenerate entanglemen…

Pump-probe Auger-electron spectroscopy of Mott insulators
Roman Rausch, Michael Potthoff
In high-resolution core-valence-valence (CVV) Auger electron spectroscopy from the surface of a solid at thermal equilibrium, the main correlation satellite, visible in the case of…
