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…
Topological Chern-Simons Sigma Model
Eunkyung Koh, Sangmin Lee, Sungjay Lee
We consider topological twisting of recently constructed Chern-Simons-matter theories in three dimensions with N=4 or higher supersymmetry. We enumerate physically inequivalent twi…
Vortex-type Half-BPS Solitons in ABJM Theory
Chanju Kim, Yoonbai Kim, O-Kab Kwon +1
We study Aharony-Bergman-Jafferis-Maldacena (ABJM) theory without and with mass deformation. It is shown that maximally supersymmetry preserving, D-term, and F-term mass deformatio…
Dyonic solution of Horava-Lifshitz Gravity
Eoin Ó Colgáin, Hossein Yavartanoo
Recently proposed Horava-Lifshitz gravity promises a UV completion of Einstein's theory by sacrificing general covariance at short distances and introducing anisotropic spacetime s…
The Trispectrum in the Multi-brid Inflation
Qing-Guo Huang
The trispectrum is at least as important as the bispectrum and its size can be characterized by two parameters and . In this short paper, we focus on the Multi-bri…
Positronium-like states from supergravity
Eoin Ó Colgáin, Hossein Yavartanoo
We study semi-classical rotating open strings ending on a probe Dp-brane close to a stack of extremal, non-extremal Dp-branes and Dp-branes with -fields. These states may be int…
