These correlations are manifested by a non-linear suppression of the Coulomb pseudogap which inhibits low energy interlayer tunneling in weakly-coupled bilayers. The pseudogap suppression is strongest at $\\nu_T=1$ and grows rapidly as the critical layer separation for exciton condensation is approached from above.", "revisions": [ { "version": "v1", "updated": "2019-03-19T21:31:13.000Z" } ], "analyses": { "keywords": [ "exciton condensation", "low energy interlayer tunneling", "hall bilayer two-dimensional electron systems", "quantum hall bilayer two-dimensional electron", "precursors" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable" } } }
