Potential Generation and Path-Integral Monte Carlo in Study of Microscopic Superfluidity

摘要

The idea of a macroscopic Andronikashvili experiment used to measure superfluid fraction of bulk liquid He-4 can be ported into the realm of spectroscopic studies to measure the superfluid fraction of microscopic systems at the nanoscale. Theoretical studies are needed to fully unravel the superfluid information contained in such a microscopic Andronikashvili experiment. Two aspects of the theoretical studies, the generation of accurate and efficient potential energy surfaces, and the methodology of path-integral Monte Carlo simulations are briefly introduced in this article.
