Using an incremental technique along physical parameters, the method significantly reduces computational cost while maintaining accuracy. Applied to a 2D square lattice Hubbard model and Gross-Neveu criticality, the approach reveals that entanglement entropy scaling follows a universal form quantified by the critical exponent ν, and that the leading coefficient decreases monotonically near the O(N) transition point rather than developing a local maximum. ## Full article daily.dev links to this article rather than hosting it.
