Summing parquet diagrams using the functional renormalization group: X-ray problem revisited
Philipp Lange, Casper Drukier, Anand Sharma +1
We present a simple method for summing so-called parquet diagrams of fermionic many-body systems with competing instabilities using the functional renormalization group. Our method…
Non-analytic magnetic field dependence of quasi-particle properties of two-dimensional metals
Casper Drukier, Philipp Lange, Peter Kopietz
We show that in a weak external magnetic field H the quasi-particle residue and the renormalized electron Lande factor of two-dimensional Fermi liquids exhibit a non-analytic magne…
Functional renormalization group approach to the Ising-nematic quantum critical point of two-dimensional metals
Casper Drukier, Lorenz Bartosch, Aldo Isidori +1
Using functional renormalization group methods, we study an effective low-energy model describing the Ising-nematic quantum critical point in two-dimensional metals. We treat both…
