QMC simulations establish a zero-temperature charge-4e superconducting phase in the attractive SU(4) Hubbard model, with the charge-2e to charge-4e transition described by deconfined pseudocriticality in an Sp(4) gauge-Higgs theory whose one-loop exponents match the numerics.
A systematic method maps interacting fermion Hamiltonians to Majorana space, classifies their continuous symmetries with semisimple Lie algebra theory, and enumerates order parameters by decomposing induced representations while adding discrete lattice symmetries.
Staggered fermion actions meet the criteria for symmetric mass generation in lattice QCD, with Goldstone tetraquark states as a signature of the type-II phase.
