Strain-induced superfluid transition for atoms on graphene
Sang Wook Kim, Mohamed Elsayed, Nathan S. Nichols +5
Bosonic atoms deposited on atomically thin substrates represent a playground for exotic quantum many-body physics due to the highly-tunable, atomic-scale nature of the interaction…
A Perspective on Collective Properties of Atoms on 2D Materials
Adrian Del Maestro, Carlos Wexler, Juan M. Vanegas +2
Atoms deposited on two-dimensional (2D) electronic materials, such as graphene, can exhibit unconventional many-body correlations, not accessible in other settings. All of these ar…
Two-Dimensional Bose-Hubbard Model for Helium on Graphene
Jiangyong Yu, Ethan Lauricella, Mohamed Elsayed +9
An exciting development in the field of correlated systems is the possibility of realizing two-dimensional (2D) phases of quantum matter. For a systems of bosons, an example of str…
Adsorption by design: tuning atom-graphene van der Waals interactions via mechanical strain
Nathan S. Nichols, Adrian Del Maestro, Carlos Wexler +1
We aim to understand how the van der Waals force between neutral adatoms and a graphene layer is modified by uniaxial strain and electron correlation effects. A detailed analysis i…
Melting of hexane monolayers adsorbed on graphite: the role of domains and defect formation
C. Wexler, L. Firlej, B. Kuchta +1
We present the first large-scale molecular dynamics simulations of hexane on graphite that completely reproduces all experimental features of the melting transition. The canonical…
Cross-over mechanism of the melting transition in monolayers of alkanes adsorbed on graphite and the universality of energy scaling
L. Firlej, B. Kuchta, M. W. Roth +1
The interplay between the torsional potential energy and the scaling of the 1-4 van der Waals and Coulomb interactions determines the stiffness of flexible molecules. In molecular…
