    "abstract": "In has been recently shown [1] that in Dirac\u0027s hole theory the vacuum state\nis not the minimum energy state but that there exist quantum states with less\nenergy than that of the vacuum state. In this paper we extend this discussion\nto quantum field theory (QFT) and consider the question of whether or not the\nvacuum in QFT is the state of minimum energy. It will be shown that for a\n\"simple\" field theory, consisting of a quantized fermion field interacting with\na classical electric field in 1-1D space-time, there exist quauntum states with\nless energy than that of the vacuum state.",
