TL;DR: This article showed that grain boundaries in 4He crystals are generically superfluid at low temperature, with a transition temperature of the order of approximately 0.5 K at the melting pressure; nonsuperfluid grain boundaries are found only for special orientations of the grains.

TL;DR: In this paper, numerically a monodisperse model of interacting classical particles predicted to exhibit a static liquid-glass transition was studied and shown to not freeze into a glassy phase at low temperatures.

TL;DR: In this article, the ground state energies and the density profiles of atomic repulsive Fermi gases in optical lattices computed via Density Functional Theory (DFT) against the results of diffusion Monte Carlo (DMC) simulations are compared.

TL;DR: The experience in preparing and publishing two specific executable papers where the VisTrails workflow system was used to embed full provenance information of the paper is reported on and open challenges and issues the authors encountered are discussed.

TL;DR: The AutoRXN workflow as mentioned in this paper is an automated workflow for exploratory high-throughput electronic structure calculations of molecular systems, in which density functional theory methods are exploited to deliver minimum and transition-state structures and corresponding energies and properties, coupled cluster calculations are then launched for optimized structures to provide more accurate energy and property estimates.
