Ammar Husain developed a general one-dimensional quantum potentials module for the HEPLean/PhysLean repository, focusing on formal verification and mathematical physics. He implemented momentum, position, and potential operators, along with a Schrödinger operator supporting general 1D potential systems. The work included rigorous proofs of operator linearity and introduced a configurable parameter structure to manage system constants such as mass and Planck’s constant. Using Lean as the primary language, Ammar ensured the module’s stability and traceability by linking changes to specific commits. The depth of the implementation reflects a strong grasp of quantum mechanics and formal methods in scientific software engineering.
