Using diffusion and path-integral Monte Carlo methods, we show that liquid $^{4}\mathrm{He}$ confined in a narrow nanopore of liquid radius $R=4\phantom{\rule{0.28em}{0ex}}\text{\AA{}}$ undergoes a crossover from a one-dimensional (1D) to a two-dimen

We present neutron scattering measurements of the phonon-roton and layer modes of liquid helium confined in 28 \AA{} diameter nanopores of FSM-16. The goal is to determine the energy, lifetime, and intensity of the modes as a function of temperature.

We report diffusion Monte Carlo (DMC) and path integral Monte Carlo (PIMC) calculations of the properties of a one-dimensional (1D) Bose quantum fluid. The equation of state, the superfluid fraction ${\ensuremath{\rho}}_{S}/{\ensuremath{\rho}}_{0}$,

Progress made in measuring and interpreting the elementary excitations of superfluid and normal liquid \4he in the past 25 years is reviewed. The goal is to bring up to date the data, calculations and our understanding of the excitations since the bo

We review the formulation and measurement of Bose-Einstein condensation (BEC) in liquid and solid helium. BEC is defined for a Bose gas and subsequently for interacting systems via the one-body density matrix (OBDM) valid for both uniform and non-uni

Ever since the seminal torsional oscillator (TO) measurements of Kim and Chan which suggested the existence of a phase transition in solid 4He, from normal to a ‘supersolid’ state below a critical temperature Tc= 200 mK, there has been an unprece

The atomic momentum distribution in quantum fluids and solids differs significantly from the classical, Gaussian Maxwell–Boltzmann distribution. There are more low momentum atoms than in a Gaussian. Using simple models, we show that deviation from

We sketch our recent neutron scattering measurements of the phonon-roton (P-R) modes and Bose-Einstein condensation (BEC) of liquid 4He in porous media. The aim is to reveal the interdependence of BEC, well-defined P-R modes and superfluidity in heli
