Abstract

Helium droplets are unique bosonic finite systems that can be studied from a few-body bound state, through droplets of thousands of particles, up to the bulk limit. They therefore provide an excellent laboratory for the study of finite-size dependence of many physical properties. Moreover, due to the simplicity of the helium-helium interaction, exact Monte Carlo simulations [1] of the ground state can be performed to critically assess the validity of approximate theoretical techniques and (semi)-phenomenological models.

In this work, we present some studies on the structural features of small liquid droplets, with particle numbers ranging from 10 to 70. We pay particular attention to excited state properties that are currently beyond the reach of Monte Carlo methods. It is shown that in many respects even very small clusters retain surprisingly bulk-like properties.
