"It’s all about the trade-offs," Elias said, reading a section on energy cutoffs. "Higher cutoff means more accuracy, but exponentially more computational cost."
Elias ran the output through a plotting script. On the screen, a graph bloomed. It was the characteristic linear dispersion of graphene near the K-point—the famous "Dirac cone." It was beautiful. It wasn't just a drawing in a book; it was a structure he had built from first principles, using the fundamental laws of quantum mechanics.
