Inelastic neutron scattering from liquid para-hydrogen by ring polymer molecular dynamics
- Abstract:
-
We investigate the use of the ring polymer molecular dynamics (RPMD) method to calculate the incoherent dynamic structure factor of liquid para-hydrogen at a temperature of 14 K. Two different approximation schemes are considered: the RPMD approximation to the self relaxation function F̃s(κ,t) and the Gaussian approximation to the intermediate scattering function F s(κ, t). We find that both approximations give similar results for low momentum transfer, but that their predictions differ appre...
