For decades, frustrated quantum magnets have been a seed for scientific progress and
innovation in condensed matter. As much as the numerical tools for low-dimensional …

Motivated by recent reports of nematic order in twisted bilayer graphene (TBG), we
investigate the impact of the triangular moiré superlattice degrees of freedom on nematicity …

Pinch point singularities, associated with flat band magnetic excitations, are tell-tale
signatures of Coulomb spin liquids. While their properties in the presence of quantum …

We analyze density wave and Pomeranchuk orders in twisted bilayer graphene. This
complements our earlier analysis of the pairing instabilities. We assume that near half filling …

We investigate the ground-state properties of the spin-1/2 pyrochlore Heisenberg
antiferromagnet using pseudofermion functional renormalization group techniques. The first …

Motivated by recent experiments on Ce 2 Zr 2 O 7 that reveal a dynamic, liquidlike ground
state, we study the nearest-neighbor XYZ Hamiltonian of dipolar-octupolar pyrochlore …

Renormalization group methods are well-established tools for the (numerical) investigation
of the low-energy properties of correlated quantum many-body systems, allowing us to …

The pseudofermion functional renormalization group (PFFRG) method has proven to be a
powerful numerical approach to treat frustrated quantum spin systems. In its usual …

The Kitaev model, whose ground state is a quantum spin liquid (QSL), was originally
conceived for spin S= 1/2 moments on a honeycomb lattice. In recent years, the model has …

The theoretical inception of the Kitaev honeycomb model has had defining influence on the
experimental hunt for quantum spin liquids, bringing unprecedented focus onto the …
