Absence of SO(4) quantum criticality in Dirac semimetals at two-loop order
Nf=2. However, this only happens very slowly, such that an extrapolation to ϵ=1 still suggests the absence of criticality in 2+1 dimensions. Thereby, we consolidate the finding that the continuum field theory [...] systems has been found in large-scale quantum Monte Carlo simulations. However, the corresponding (2+1)-dimensional Gross--Neveu--Yukawa field theory with Nf=2 four-component Dirac fermions coupled to two …
