Projective symmetry group classification of chiral spin liquids on the pyrochlore lattice: application to the spin- XXZ Heisenberg model
Benedikt Schneider, Jad C. Halimeh, Matthias Punk
We give a complete classification of fully symmetric as well as chiral quantum spin liquids on the pyrochlore lattice using a projective symmetry group analysis of S…
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…
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…
Solvable lattice models for metals with Z2 topological order
Brin Verheijden, Yuhao Zhao, Matthias Punk
We present quantum dimer models in two dimensions which realize metallic ground states with Z2 topological order. Our models are generalizations of a dimer model introduced in [PNA…
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…
