However it has recently been demonstrated that this is not necessarily the case for some situations [5]. In order to clarify the situation we will consider a \"very simple\" field theory in the Heisenberg picture consisting of a quanitized fermion field with zero mass pariticles in 1-1D space-time interacting with a classical electrical potential. It will be shown that for this example there is no lower bound to the energy.", "revisions": [ { "version": "v1", "updated": "2008-08-20T17:01:14.000Z" } ], "analyses": { "keywords": [ "lower bound", "heisenberg picture", "interesting result concerning", "zero mass pariticles", "special state" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0808.2786S" } } }
