The operator is a Weyl quantisation of the classical Hamiltonian for an inverted harmonic oscillator, producing a difference operator on a finite, periodic lattice. We investigate the continuum and the infinite-volume limit of our model in conjunction with the semiclassical limit. Using semiclassical methods, we show that a specific combination of the limits leads to a logarithmic mean spectral density as it was anticipated by Berry and Keating.", "revisions": [ { "version": "v1", "updated": "2016-10-20T16:02:28.000Z" } ], "analyses": { "keywords": [ "berry-keating operator", "logarithmic mean spectral density", "built-in truncation", "periodic lattice", "infinite-volume limit" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
