Gas–Solid Transition of Quantum Particles Interacting with Inverse-Power-Law Repulsive Potential

摘要

We study the gas–solid phase diagram of quantum particles interacting with the inverse-power-law repulsive interaction. It is found that the solid phase is promoted by the quantum effect in the intermediate region where the quantum effect is not yet dominant but is nonnegligible. We further find that a weak minimum in the coexistence pressure curve appears at low temperatures.
