Constraining the transport properties of dense liquid hydrogen is needed to model the internal dynamics of gas giants. Here, we calculate the diffusion, viscosity, and heat capacity of liquid hydrogen from first principles simulations. Our calculations consider both nuclear quantum effects and nonlocal exchange-correlation density functionals, which are known to greatly alter the pre-existing phase diagram of this system.
