14 Nov 2000 | | Journal: | Physical Review Letters 86, 2617 (2001) DOI: 10.1103/PhysRevLett.86.2617 | | Subject: | Strongly Correlated Electrons; Superconductivity | cond-mat.str-el cond-mat.supr-con | | Affiliation: | Yale), Matthias Troyer (ETH, Zurich) and Matthias Vojta (Augsburg | | Abstract: | We compute the spectral function of a spin S hole injected into a two-dimensional antiferromagnet or superconductor in the vicinity of a magnetic quantum critical point. We show that, near van Hove singularities, the problem maps onto that of a static vacancy carrying excess spin S. The hole creation operator is characterized by a new boundary anomalous dimension and a vanishing quasiparticle residue at the critical point. We discuss possible relevance to photoemission spectra of cuprate superconductors near the anti-nodal points. | | Source: | arXiv, cond-mat/0011232 | | Other source: | [GID 491643] pmid11289994 | | Services: | Forum | Review | PDF | Favorites | |
