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…
Torus Spectroscopy of the Gross-Neveu-Yukawa Quantum Field Theory: Free Dirac versus Chiral Ising Fixed Point
Michael Schuler, Stephan Hesselmann, Seth Whitsitt +3
We establish the universal torus low-energy spectra at the free Dirac fixed point and at the strongly coupled chiral Ising fixed point and their subtle crossover behaviour in the G…
