Benchmark calculations on high-dimensional Henon–Heiles potentials with the multi-configuration time dependent Hartree (MCTDH) method

We present quantum dynamical simulations on generalized, high-dimensional Henon–Heiles potentials. The calculations can serve as benchmark results for other, approximative methods. Especially, we will give a comparison with semiclassical and Gaussian wave packet Monte Carlo calculations from two other groups. The scaling behavior of the multi-configuration time dependent Hartree method with the dimensionality of the problem is investigated and discussed.
