Specifically we calculate the vacuum expectation value of the field square, $<\\Phi^2>$. Because this investigation has been developed in a pure de Sitter space, here we are mainly interested on the effects induced by the presence of the defects.", "revisions": [ { "version": "v1", "updated": "2010-02-23T16:59:27.000Z" } ], "analyses": { "keywords": [ "sitter spacetime", "topological defects", "massive quantum scalar field", "vacuum expectation value", "field square" ], "tags": [ "conference paper", "journal article" ], "publication": { "doi": "10.1088/1742-6596/222/1/012034", "journal": "Journal of Physics Conference Series", "year": 2010, "month": "Apr", "volume": 222, "number": 1, "pages": "012034" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 846306, "adsabs": "2010JPhCS.222a2034B" } } }
