“…One strategy for overcoming this problem is to find more efficient truncation subspaces that lead to faster convergence. For instance, in [29], the authors studied 2d φ 4 theory using DLCQ, and with improved algorithms and computational resources the authors were able to take the truncation parameter K = 96, corresponding to about 60 million states. Such a large truncation made it possible to reliably establish that the truncation error in the critical coupling λ c converged to zero like O( 1 √ K ) as K → ∞.…”
