Abstract

We present a first-principles density-functional study of the free surface of a Bose Lennard-Jones (BLJ) fluid at zero temperature. Following the Weeks-Chandler-Andersen perturbation scheme for classical LJ fluids, we treat the repulsive part of the BLJ by a Bose hard-sphere (BHS) reference system, where the equivalent BHS diameter is taken from the approach of Kalos, Levesque, and Verlet [Phys. Rev. A 9, 2178 (1974)]. When the de BoerMichels parameters of He4 are chosen for the BLJ fluid, the calculated surface properties are in good agreement with those from experiment and Monte Carlo simulation.
