On the Phase Diagrams of 4He Adsorbed on Graphene and Graphite from Quantum Simulation Methods

The ground-state phase diagrams of 4 He adsorbed on graphene and graphite are calculated using quantum simulation methods. In this work, a systematic investigation of the approximations used in such simulations is carried out. Particular focus is placed on the helium–helium (He&...
