Functional renormalization group approach to phonon modified criticality: anomalous dimension of strain and non-analytic corrections to Hooke's law
Max O. Hansen, Julia von Rothkirch, Peter Kopietz
We study the interplay between critical isotropic elasticity and classical Ising criticality using a functional renormalization group (FRG) approach which is implemented such that…

Non-Fermi liquid fixed point of the dissipative Yukawa-Sachdev-Ye-Kitaev model
Niklas Cichutek, Andreas Rückriegel, Peter Kopietz
Using a functional renormalization group approach we derive the renormalization group (RG) flow of a dissipative variant of the Yukawa-Sachdev-Ye-Kitaev model describing fermio…
