Fermi and Luttinger arcs: two concepts, realized on one surface
Paul Worm, Matthias Reitner, Karsten Held +1
We present an analytically solvable model for correlated electrons, which is able to capture the major Fermi surface modifications occurring in both hole- and electron-doped cuprat…
Interacting nodal semimetals with non-linear bands
Arianna Poli, Niklas Wagner, Max Fischer +3
We investigate the quasi-particle and transport properties of a model describing interacting Dirac and Weyl semimetals in the presence of local Hubbard repulsion , where we expl…
Thermodynamic Stability at the Two-Particle Level
A. Kowalski, M. Reitner, L. Del Re +6
We show how the stability conditions for a system of interacting fermions that conventionally involve variations of thermodynamic potentials can be rewritten in terms of one- and t…
Entangled magnetic, charge, and superconducting pairing correlations in the two-dimensional Hubbard model: a functional renormalization-group analysis
Sarah Heinzelmann, Alessandro Toschi, Sabine Andergassen
Using the recently introduced multiloop extension of the functional renormalization group, we compute the magnetic, density, and superconducting susceptibilities of the two-dimensi…
Protection of Correlation-Induced Phase Instabilities by Exceptional Susceptibilities
Matthias Reitner, Lorenzo Crippa, Dominik Robert Fus +3
At thermal equilibrium, we find that generalized susceptibilities encoding the static physical response properties of Hermitian many-electron systems possess inherent non-Hermitian…
Highly nonperturbative nature of the Mott metal-insulator transition: Two-particle vertex divergences in the coexistence region
Mathias Pelz, Severino Adler, Matthias Reitner +1
We thoroughly analyze the divergences of the irreducible vertex functions occurring in the charge channel of the half-filled Hubbard model in close proximity to the Mott metal-insu…
