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…
Functional renormalization group without functional integrals: implementing Hilbert space projections for strongly correlated electrons via Hubbard X-operators
Andreas Rückriegel, Jonas Arnold, Rüdiger Krämer +1
Exact functional renormalization group (FRG) flow equations for quantum systems can be derived directly within an operator formalism without using functional integrals. This simple…
Collective modes in the charge-density wave state of KMoO: The role of long-range Coulomb interactions revisited
Max O. Hansen, Yash Palan, Viktor Hahn +7
We re-examine the effect of long-range Coulomb interactions on the collective amplitude and phase modes in the incommensurate charge-density-wave ground state of quasi-one-dimensio…
