Mazumdar, Anupam and M. Sheikh-Jabbari, Mohammad (2001) Noncommutativity in Space and Primordial Magnetic Field. Physical review letters, 87 (1): 011301. ISSN 1079-7114
Abstract
In this paper we show that noncommutativity in spatial coordinates can generate magnetic field in the early Universe on a horizon scale. The strength of such a magnetic field depends on the number density of massive charged particles present at a given moment. This allows us to trace back the temperature dependence of the noncommutativity scale from the bounds on primordial magnetic field coming from nucleosynthesis.
