Dynamical Compactification and Inflation in Einstein-Yang-Mills Theory with Higher Derivative Coupling
Hironobu Kihara, Muneto Nitta, Misao Sasaki +2
We study cosmology of the Einstein-Yang-Mills theory in ten dimensions with a quartic term in the Yang-Mills field strength. We obtain analytically a class of cosmological solution…
Fractional Vortices and Lumps
Minoru Eto, Toshiaki Fujimori, Sven Bjarke Gudnason +5
We study what might be called fractional vortices, vortex configurations with the minimum winding from the viewpoint of their topological stability, but which are characterized by…
Non-Abelian Vortices in SO(N) and USp(N) Gauge Theories
Minoru Eto, Toshiaki Fujimori, Sven Bjarke Gudnason +5
Non-Abelian BPS vortices in SO(N) x U(1) and USp(2N) x U(1) gauge theories are constructed in maximally color-flavor locked vacua. We study in detail their moduli and transformatio…
Dynamics of Strings between Domain Walls
Minoru Eto, Toshiaki Fujimori, Takayuki Nagashima +3
Configurations of vortex-strings stretched between or ending on domain walls were previously found to be 1/4 BPS states. Among zero modes of string positions, the center of mass of…
Dynamics of Strings between Walls
Minoru Eto, Toshiaki Fujimori, Takayuki Nagashima +3
Configurations of vortex-strings stretched between or ending on domain walls were previously found to be 1/4 Bogomol'nyi-Prasad-Sommerfield(BPS) states in N=2 supersymmetric gauge…
Brane Vector Dynamics from Embedding Geometry
T. E. Clark, S. T. Love, Muneto Nitta +2
A Kaluza-Klein decomposition of higher dimensional gravity is performed in the flexible brane world scenario and the properties of the extra vectors resulting from this decompositi…
