Ground state properties of soft core bosons on a two-dimensional honeycomb lattice
We study the ground state properties of interacting bosons on a 2 dimensional honeycomb lattice using SSE QMC simulations with directed loop update. We pay particular attention to the supersolid phase. At maximum occupancy of 2 bosons per site, we observe a ρ = 1/2 solid which undergoes a continuous...
