What Does CSFGH Stand For?

CSFGH stands for Complex Scaling Fourier Grid Hamiltonian

CSFGH, or Complex Scaling Fourier Grid Hamiltonian, is an advanced computational method used in quantum mechanics to analyze and solve problems involving complex potentials. This technique employs a Fourier grid approach combined with complex scaling transformations to efficiently compute eigenvalues and eigenfunctions of Hamiltonian operators. By facilitating the treatment of non-Hermitian systems, CSFGH is particularly useful in studies of resonances and decay processes in quantum systems, making it a valuable tool in theoretical and applied physics research.
