Exchange-driven self-diffusion of nanoscale crystalline parahydrogen clusters on graphite
K. M. Kolevski, M. Boninsegni
Computer simulations yield evidence of superfluid behavior of nanoscale size clusters of parahydrogen adsorbed on a graphite substrate at low temperature ($T\lesssim 0.25 \text{ K}…
Superfluidity of quasi-2D He-4 droplets on graphite
K. M. Kolevski, M. Boninsegni
The superfluid response of nanoscale size quasi-2D He-4 droplets adsorbed on a graphite substrate is investigated by computer simulations. It is found that clusters comprising as f…
Momentum distribution of He-3 in one dimension
Massimo Boninsegni
The one-particle density matrix of a one-dimensional system of fermions featuring a hard-core repulsive interaction at short distances can be computed (numerically) exactly by mean…
He-4 monolayer on Graphene: a Quantum Monte Carlo study
Siyuan Yu, Massimo Boninsegni
We revisit the problem of adsorption of a single He-4 layer on graphene, focusing on the commensurate C1/3 crystalline phase, specifically on whether it may possess a nonzero super…
Quantum Monte Carlo study of thin parahydrogen films on graphite
Jie-Ru Hu, Massimo Boninsegni
The low-temperature properties of one and two layers of parahydrogen adsorbed on graphite are investigated theoretically through Quantum Monte Carlo simulations. We adopt a microsc…
