Analogue non-Riemannian black holes in vortical moving plasmas | L.C. Garcia de Andrade
; | Date: |
11 Sep 2005 | Subject: | gr-qc | Abstract: | Analogue black holes in non-Riemannian effective spacetime of moving vortical plasmas described by moving magnetohydrodynamic (MHD) flows. This example is an extension of acoustic torsion recently introduced in the literature (Garcia de Andrade,PRD(2004),7,64004), where now the presence of artificial black holes in moving plasmas is obtained by the presence of an horizon in the non-Riemannian spacetime. Hawking radiation is computed in terms of the background magnetic field and the magnetic permeability. The metric is singular although Cartan analogue torsion is not necessarily singular. The effective Lorentz invariance is shown to be broken due to the presence of effective torsion in strong analogy with the Riemann-Cartan gravitational case presented recently by Kostelecky (PRD 69,2004,105009). | Source: | arXiv, gr-qc/0509034 | Services: | Forum | Review | PDF | Favorites |
