MCViNE is an open source, object-oriented Monte Carlo neutron ray-tracing simulation
software package. Its design allows for flexible, hierarchical representations of sophisticated …

Liquid-helium temperature is a widely used working temperature in low-temperature
physics. At present, liquid-helium or low-frequency cryocoolers, including Gifford Mahon …

The dynamic structure factor of superfluid He 4 has been investigated at very low
temperatures by inelastic neutron scattering. The measurements combine different incoming …

We review fundamental problems involved in liquid theory including both classical and
quantum liquids. Understanding classical liquids involves exploring details of their …

We present an inelastic neutron scattering study of liquid and solid hydrogen carried out
using the wide Angular Range Chopper Spectrometer at Oak Ridge National Laboratory …

In a superfluid system, off-diagonal long-range order is expected to be exhibited in the
appropriate reduced density matrices when the relevant particles (either bosons or fermion …

Short-range correlations in bosonic Helium clusters, composed of He 4 atoms, are studied
utilizing the generalized contact formalism. The emergence of universal n-body short-range …

The thermodynamics of solid (hcp) 4 He is studied theoretically by means of unbiased Monte
Carlo simulations at finite temperature, in a wide range of density. This study complements …

This contribution describes the computational methodology behind an optimization
procedure for a scattered beam collimator. The workflow includes producing a file that can …

We report on an inelastic neutron scattering study of the proton dynamics in ZrH 0.0155 and
ε-ZrH 2. In particular, we present measurements of the incoherent dynamic structure factor …
