Chiral Heisenberg Gross-Neveu-Yukawa criticality: Honeycomb vs. SLAC fermions
Thomas C. Lang, Andreas M. Läuchli
We perform large scale quantum Monte Carlo simulations of the Hubbard model at half filling with a single Dirac cone close to the critical point, which separates a Dirac semi-metal…
Non-coplanar magnetism, topological density wave order and emergent symmetry at half-integer filling of moiré Chern bands
Patrick H. Wilhelm, Thomas C. Lang, Mathias S. Scheurer +1
Twisted double- and mono-bilayer graphene are graphene-based moiré materials hosting strongly correlated fermions in a gate-tunable conduction band with a topologically non-trivial…
Programmable quantum simulation of 2D antiferromagnets with hundreds of Rydberg atoms
Pascal Scholl, Michael Schuler, Hannah J. Williams +9
Quantum simulation using synthetic systems is a promising route to solve outstanding quantum many-body problems in regimes where other approaches, including numerical ones, fail. M…
Interplay of Fractional Chern Insulator and Charge-Density-Wave Phases in Twisted Bilayer Graphene
Patrick Wilhelm, Thomas C. Lang, Andreas M. Läuchli
We perform an extensive exact diagonalization study of interaction driven insulators in spin- and valley-polarized moiré flat bands of twisted bilayer graphene aligned with its hex…
Comment on "The role of electron-electron interactions in two-dimensional Dirac fermions''
Stephan Hesselmann, Thomas C. Lang, Michael Schuler +2
Tang et al. [Science 361, 570 (2018)] report on the properties of Dirac fermions with both on-site and Coulomb interactions. The substantial decrease up to ~40% of the Fermi veloci…
Quantifying the fragility of unprotected quadratic band crossing points
Stephan Hesselmann, Carsten Honerkamp, Stefan Wessel +1
We examine a basic lattice model of interacting fermions that exhibits quadratic band crossing points (QBCPs) in the non-interacting limit. In particular, we consider spinless ferm…
