Ab initio simulation study of collective excitations in a molecular hydrogen fluid

Year: 2025

Type: article

Abstract: We report a theoretical analysis of collective dynamics in a molecular Hydrogen fluid performed within a combination of ab initio molecular dynamics (AIMD) simulations and the approach of Generalized collective Modes (GCM).A five-variable thermo-viscoelastic model of generalized hydrodynamics was applied to recover four different collective time correlation functions, obtained from AIMD.Dispersion of collective excitations in a molecular Hydrogen fluid, obtained from peak positions of the current spectral functions as well as from the GCM eigenvalues, is reported.
