Multiloop pseudofermion functional renormalization for quantum spin systems: Application to the spin- kagome Heisenberg model
Julian Thoenniss, Marc K. Ritter, Fabian B. Kugler +2
We present a multiloop pseudofermion functional renormalization group (pffRG) approach to quantum spin systems. As a test case, we study the spin- Heisenberg model on…

A slave boson description of pseudogap metals in t-J models
Julia Brunkert, Matthias Punk
We present a simple modification of the standard U(1) slave boson construction for the single band t-J model which accounts for two-particle bound states of spinons and holons. Thi…
