We revis.t the problem of ads.rption of a s.ngle4He layer on graphene, focus.ng on the commens.rate(C1/3) crys.alline phas., s.ecifically on whether it may pos.es. a nonzero s.perfluid res.ons., and on the exis.ence of s.perfluid phas.s. either（metas.able） liquid or vacancy-doped crys.alline. We make us. of canonical quantum monte Carlo s.mulations.at zero and finite temperature, bas.d on a realis.ic micros.opic model of the s.s.em. Our res.lts.confirm the abs.nce of any s.perfluid res.ons. in the commens.rate crys.al, and that no thermodynamically s.able uniform phas. exis.s.at lower coverage. No evidence of a pos.ibly long-lived, metas.able s.perfluid phas. at C1/3coverage is.found. Altogether, the res.lts.of ground-s.ate projection methods.and finite-temperature s.mulations.are entirely cons.s.ent.
