What Does FGH Stand For?

FGH stands for Fourier Grid Hamiltonian

FGH, or Fourier Grid Hamiltonian, is a numerical method used in quantum mechanics and computational physics to solve the Schrödinger equation. It involves discretizing the spatial domain on a grid and applying the Fourier transform to efficiently compute the Hamiltonian operator in momentum space. This approach allows for the accurate simulation of quantum systems, facilitating the analysis of various physical phenomena, including molecular dynamics and tunneling effects, while optimizing computational resources and improving performance.
