  We describe Bose-Einstein condensation of strongly interacting particles into
a quantum state which is an excited single-particle state, but becomes the
ground state as density increases because it minimizes the interaction energy
compared to other states. Mean field calculations for a graphene potential just
wide enough for two closely interacting layers of molecular hydrogen show
condensation at temperatures up to 60 K. In the condensed state, molecules hop
between layers, increasing the first peak in the pair-correlation function just
past the hard core repulsion diameter.
