A scalar field with logarithmic correlations (such as a massless field in 1+1 spacetime dimensions) has the mildest of singularities, making it a logical starting point. Instead of the usual inner product of the field with a smooth function, we introduce a moving average on an interval which allows us to obtain explicit results and has a simple physical interpretation. Using the mathematical work of Dudley, we prove that the averaged random process is in fact continuous, and give a precise modulus of continuity bounding the short-distance variation.", "revisions": [ { "version": "v1", "updated": "2015-08-19T14:20:30.000Z" } ], "analyses": { "keywords": [ "logarithmic correlations", "scalar field", "continuity", "scalar quantum fields", "usual inner product" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
