Zero-Point Motion of Liquid and Solid Hydrogen
T. R. Prisk, R. T. Azuah, D. L. Abernathy +5
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. From t…
A Parameter-Free Differential Evolution Algorithm for the Analytic Continuation of Imaginary Time Correlation Functions
Nathan S. Nichols, Paul Sokol, Adrian Del Maestro
We report on Differential Evolution for Analytic Continuation (DEAC): a parameter-free evolutionary algorithm to generate the dynamic structure factor from imaginary time correlati…
Dimensional Reduction of Helium-4 Inside Argon Plated MCM-41 Nanopores
Nathan Nichols, Timothy R. Prisk, Garfield Warren +2
The angstrom-scale coherence length describing the superfluid wavefunction of helium-4 at low temperatures has prevented its preparation in a truly one-dimensional geometry. Mesopo…
Maxon and roton measurements in nanoconfined He
Matthew S. Bryan, Paul E. Sokol
We investigate the behavior of the collective excitations of adsorbed He in an ordered hexagonal mesopore, examining the crossover from a thin film to a confined fluid. Here we…
The Momentum Distribution of Liquid He
Timothy R. Prisk, Matthew S. Bryan, Paul. E. Sokol +3
We report high-resolution neutron Compton scattering measurements of liquid He under saturated vapor pressure. There is excellent agreement between the observed scattering and…
Phases of Superfluid Helium in Smooth Cylindrical Pores
T. R. Prisk, N. C. Das, S. O. Diallo +5
Two different microscopic phases have been observed via inelastic neutron scattering for superfluid helium confined within highly monodisperse, smooth, and unidimensional silica po…
