Islands in Proliferating de Sitter Spaces
Jong-Hyun Baek, Kang-Sin Choi
We study two-dimensional de Sitter universe which evolves and proliferates according to the Ginsparg-Perry-Bousso-Hawking mechanism, using Jackiw-Teitelboim gravity coupled to conf…
Post-Newtonian Feasibility of the Closed String Massless Sector
Kang-Sin Choi, Jeong-Hyuck Park
We perform post Newtonian analysis of Double Field Theory as a test of string theory in gravitational sector against observations. We identify the Eddington--Robertson--Schiff para…
Aligned Natural Inflation in the Large Volume Scenario
Stephen Angus, Kang-Sin Choi, Chang Sub Shin
We embed natural inflation in an explict string theory model and derive observables in cosmology. We achieve this by compactifying the type IIB string on a Calabi-Yau orientifold,…
Small-Instanton Transitions in F-theory
Stephen Angus, Kang-Sin Choi
We study the phase transition between G-instantons and D3-branes. A G-instanton is a classical solution to the self-dual equation of the M/F-theory four-form field strength G in th…
Transitions of Orbifold Vacua
Kang-Sin Choi, Tatsuo Kobayashi
We study the global structure of vacua of heterotic strings compactified on orbifolds (N=2,3) in the presence of heterotic 5-branes. Gauge symmetry breaking associated wi…
Elliptic Genus, Anomaly Cancellation and Heterotic M-theory
Kang-Sin Choi, Soo-Jong Rey
We derive global consistency condition for strongly coupled heterotic string in the presence of M5-branes. Its elliptic genus is interpretable as generating functional of anomaly p…
