Hamiltonian

qsims simulates quantum dynamics with an (almost) arbitrary time-dependent Hamiltonian. qsims uses a Chebychev polynomial expansion of the Schrodinger propagator, and the pseudospectral method developed by R. Kosloff. Platforms: Mac, BSD

The FIT-MART Launcher package is a self-contained file for simulating systems of interacting quantum magnetic moments ("spins"). The interactions are modeled using the Heisenberg model, calculations are carried out by numerically diagonalizing the matrix representation of the Heisenberg... Platforms: Mac
