1. Quantum material calculations do not derive simple equations; rather, they numerically solve complex approximations of the Schrödinger equation using supercomputers. Much like a climate simulation, they recreate a “virtual laboratory” to observe how electrons behave under specific conditions. In practice, they function as numerical experiments that mimic reality, not as pure theory.
2. There is an intuitive notion that everything related to quantum physics belongs to abstract theory and pure mathematics. Furthermore, since computational modeling does not deal with physical objects, it is often easy to confuse it with the formulation of theoretical principles. Finally, many people assume that “simulation” applies only to macroscopic, tangible systems, ignoring the fact that matter at the atomic scale is also simulated using algorithms.
