Localization Problem in the 5D Standing Wave Braneworld
Merab Gogberashvili, Pavle Midodashvili, Levan Midodashvili
We investigate the problem of pure gravitational localization of matter fields within the 5D standing wave braneworld generated by gravity coupled to a phantom-like scalar field. W…
Negative Modes of Oscillating Instantons
Lorenzo Battarra, George Lavrelashvili, Jean-Luc Lehners
We investigate in detail the properties of oscillating instanton solutions discussed recently in the literature. We find that the solutions with N nodes contain exactly N homogeneo…
Localization of Matter Fields in the 5D Standing Wave Braneworld
Merab Gogberashvili
We investigate the localization problem of matter fields within the 5D standing wave braneworld. In this model the brane emits anisotropic waves into the bulk with different amplit…
Anisotropic Inflation in a 5D Standing Wave Braneworld and Dimensional Reduction
Merab Gogberashvili, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon +1
We investigate a cosmological solution within the framework of a 5D standing wave braneworld model generated by gravity coupled to a massless scalar phantom-like field. By obtainin…
Thick Brane Isotropization in a Generalized 5D Anisotropic Standing Wave Braneworld Model
Merab Gogberashvili, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon +2
We study a smooth cosmological solution within a generalized 5D standing wave braneworld modeled by gravity and a phantom scalar field. In this model the 3-brane is anisotropically…
