Quadratic-band-touching Hamiltonians in 2D possess USp(2N) symmetry; respecting interactions are limited to two terms that either preserve the symmetry or break it to USp(N) x USp(N), while lattice versions reduce to U(N) symmetry.
Time evolution in the time-dependent SU(2) Gross-Neveu model with RG-matched coupling is equivalent to renormalization group flow, generating an exponentially decaying dynamical mass gap in the adiabatic regime.
Charm and bottom quark masses are extracted as 1275.8 ± 0.4 MeV and 4177.0 ± 7.2 MeV using PMC-improved conformal series from quarkonium sum-rule moments, agreeing with PDG averages within 1σ.
