Path integral Monte Carlo simulations and their relation to recent advances in nanophysics
… three parts. In part one an introduction to the path integral Monte Carlo method (PIMC) and an overview on the experimental techniques for making nanoscopic semiconductor structures are given. Part two consists of two already published articles on the application of PIMC to nanoscopic quantum …

Path Integral Monte Carlo Simulations of Helium: From Superfluid Droplets to Quantum Crystals
Finally, we have calculated the Deybe-Waller factor in solid helium for a range of temperatures and densities, and compared the scaling behavior with the predictions of harmonic theory. The first non-Gaussian contribution to the density distribution was calculated.

Path Integral Monte Carlo Simulations of Helium: From Superfluid Droplets to Quantum Crystals
… in microscopic, inhomogeneous helium systems. Path Integral Monte Carlo is a powerful method for calculating the equilibrium properties of quantum systems at finite temperature. We have achieved linear scaling of computer time with number of particles through the use of neighbor lists, allowing …

Path integral Monte Carlo simulations of solid H2 surfaces and thin 4He films on H2 substrates
… P. Feynman's formulation of quantum mechanics, Path Integral Monte Carlo is a computational ab-initio method to calculate finite temperature equilibrium properties of quantum many-body systems. As input, only fundamental physical constants and pair-potentials are required. We carry out the first …

Path integral Monte Carlo and the electron gas
Path integral Monte Carlo is a proven method for accurately simulating quantum mechanical systems at finite-temperature. By stochastically sampling Feynman's path integral representation of the quantum many-body density matrix, path integral Monte Carlo includes non-perturbative effects like …
