On Black Ring with a Positive Cosmological Constant
Chong-Sun Chu, Shou-Huang Dai
We consider black ring with a cosmological constant in the five dimensional N=4 de Sitter supergravity theory. Our solution preserves half of the de Sitter supersymmetries and has…
SUSY breaking by a metastable ground state: Why the early Universe preferred the non-supersymmetric vacuum
Steven A. Abel, Chong-Sun Chu, Joerg Jaeckel +1
Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum ev…
Noncommutativity from the string perspective: modification of gravity at a mm without mm sized extra dimensions
Steven Abel, Chong-Sun Chu, Mark Goodsell
We explore how the IR pathologies of noncommutative field theory are resolved when the theory is realized as open strings in background B-fields: essentially, since the IR singular…
Magnons, Classical Strings and beta-Deformations
Chong-Sun Chu, George Georgiou, Valentin V. Khoze
Motivated by the recent work of Hofman and Maldacena we construct a classical string solution on the beta-deformed AdS_5 \times \tilde{S}^5 background. This string solution is iden…
String theory dual of the beta-deformed gauge theory
Chong-Sun Chu, Valentin V. Khoze
We consider the AdS/CFT correspondence between the beta-deformed supersymmetric gauge theory and the type IIB string theory on the Lunin-Maldacena background. Guided by gauge theor…
Non-local Matching Condition and Scale-invariant Spectrum in Bouncing Cosmology
Chong-Sun Chu, Ko Furuta, Feng-Li Lin
In cosmological scenarios such as the pre-big bang scenario or the ekpyrotic scenario, a matching condition between the metric perturbations in the pre-big bang phase and those in…
