TECHNICAL COMMENT ABSTRACTS
Comment on “The role of electron-electron
interactions in two-dimensional Dirac fermions”
S. Hesselmann, T. C. Lang, M. Schuler, S. Wessel,
A. M. Läuchli
Tang et al. (Research Articles, 10 August
2018, p. 570) report on the properties of Dirac
fermions with both on-site and Coulomb
interactions. The substantial decrease, up to
~40%, of the Fermi velocity of Dirac fermions
with on-site interaction is inconsistent with
the numerical data near the Gross-Neveu
quantum critical point. This results from an
inappropriate finite-size extrapolation.

Response to Comment on “The role of electron-
electron interactions in two-dimensional
Dirac fermions”
Ho-Kin Tang, J. N. Leaw, J. N. B. Rodrigues,
I. F. Herbut, P. Sengupta, F. F. Assaad, S. Adam
Hesselmann et al. question one of our con-
clusions: the suppression of Fermi velocity
at the Gross-Neveu critical point for the
specific case of vanishing long-range inter-
actions and at zero energy. The possibility
they raise could occur in any finite-size
extrapolation of numerical data. Although
we cannot definitively rule out this possibil-
ity, we provide mathematical bounds on
its likelihood.
