The present paper investigates this dynamics for a particularly simple class of \"k-compact\" wave packets, in which the spread over different k-values is minimized, and which propagate with an essentially rigid shape through k-space.", "revisions": [ { "version": "v1", "updated": "2003-10-01T19:58:25.000Z" } ], "analyses": { "keywords": [ "wave packet dynamics", "biased finite-length superlattice", "bloch wave number form", "superposition wave packet", "multiple bloch waves" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
