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…
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…
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…
