Here we consider a circuit where the path from source to drain necessarily passes through a segment consisting solely of neutral modes. Surprisingly, we find that upon biasing the source, a dc current is detected at the drain. Thus, neutral modes carry information that can be used to nonlocally reconstruct a dc charge current. We conclude with a possible experimental realization of this phenomenon.", "revisions": [ { "version": "v1", "updated": "2021-03-10T17:23:37.000Z" } ], "analyses": { "keywords": [ "upstream neutral modes", "dc electrical current", "support chiral edge modes", "neutral modes carry information", "quantum hall phases" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable" } } }
