Holmlid's Inverted Rydberg hydrogen in not an ion, per se. But to answer Robin's question, the "decrease in volume" would be the end-game event which destroys the 2D form, allowing ZPE coherence.
BTW - Out of respect to a famous scientist, Rydberg's name should be spelled correctly (and as a notoriously bad speller, I appreciate the extra effort to get names spelled correctly, especially in the Subject heading). According to my understanding of Holmlid, Miley, Lawandy, etc. "spillover hydrogen" can collect in two dimensions ONLY on a dielectric surface in the form of protons with mirror charge. The balancing negative charge is "in" the dielectric itself, and the protons are essentially bare on the surface of the dielectric held there by electrostatic forces. The thickness of a single proton is considered to make the "snowflake" 6-fold symmetry flat structure stable in two dimensions, but no further thickness is permitted. This 2D structure can probably contort into an open ended "pit" near the surface but because it is 2D it would seem unlikely to be transported into a subsurface cavity as the 'charge balancing' would be difficult to imagine and it would gain dimensionality. A "Casimir Pit" has advantages over a cavity since it allows unimpeded acceleration out of the open end.
