    Well, a quick search turned up this: Vacuum Arc

    However, like the above comment, it seems to refer to freeing electrons from the conducts, so, IMHO, you no longer have a vacuum.

    If you could somehow maintain a perfect vacuum; I wonder how this concept Virtual particle would come into play (or if it would at all).
