Abstract Path-integral Monte Carlo simulations have been used to determine the phase
diagram of a two-dimensional 4 He film in a range of temperatures and coverages where it …

This year is also the 50th anniversary of the discovery of exfoliated graphite as a particularly
uniform substrate (Thomy and Duval in J Chim Phys 66: 1966, 1969. https://doi …

An exciting development in the field of correlated systems is the possibility of realizing two-
dimensional (2D) phases of quantum matter. For a system of bosons, an example of strong …

We have developed a cryogenic pulsed laser deposition (PLD) system to deposit lithium
films onto a quartz crystal microbalance (QCM) at 4 K. Adsorption isotherms of 4 He on …

The superfluidity of 4 He films adsorbed on the atomically flat surface of graphite, preplated
with HD to tune the surface binding potential, has been studied using a torsional oscillator …

Adsorption of 4 He on graphene substrates has been a topic of great interest due to the
intriguing effects of graphene corrugation on the manifestation of commensurate solid and …

We perform path-integral Monte Carlo calculations to study the adsorption of He 4 atoms on
a H 2-plated C 20 molecular surface. It is found that 32 H 2 molecules form a complete solid …

Nanoporous activated carbons generate interest for their gas storage and separation
potential. Generally, adsorbents are assumed rigid, even though they are formed by feeble …

The standard theory of the dynamics of superfluid films, although in good qualitative
agreement with experiment, is not in perfect quantitative agreement. Until now it has not …

We analyse recent observations, using a torsional oscillator, of the superfluid transition of a
fluid 4 He bilayer, within the framework of a modified dynamic theory of the Kosterlitz …
