Bianchi type-I cosmological string model in the presence of a magnetic field: classical an quantum loop approaches |
Cosmic strings are expected generically formed in the Early Universe as topological defects as a result of a series of phase transitions related to the spontaneous breaking of internal symmetry. A Bianchi type-I cosmological string model in the presence of a magnetic field is investigated. A few plausibly assumptions are introduced and their outcomes are discussed using numerical and qualitative analyzes. Quantum effects of a cosmological string are examined in the framework of loop quantum cosmology. |
