Spectral representation of Matsubara n-point functions: Exact kernel functions and applications
Johannes Halbinger, Benedikt Schneider, Björn Sbierski
In the field of quantum many-body physics, the spectral (or Lehmann) representation simplifies the calculation of Matsubara n-point correlation functions if the eigensystem of a Ha…

Quenched disorder at antiferromagnetic quantum critical points in metals
Johannes Halbinger, Matthias Punk
We study spin density wave quantum critical points in two dimensional metals with a quenched disorder potential coupling to the electron density. Adopting an -expansion around t…

Incommensurate density wave quantum criticality in two dimensional metals
Johannes Halbinger, Dimitri Pimenov, Matthias Punk
We revisit the problem of two dimensional metals in the vicinity of a quantum phase transition to incommensurate charge density wave order, where the order parame…
