Exact Four-Parameter Rotating NS--NS Vacuum in Double Field Theory
Hun Jang, Minkyoo Kim, Jeong-Hyuck Park
We construct an exact rotating vacuum of the NS--NS sector, equivalently a Double Field Theory vacuum. The construction applies compact S-duality to a rotating Ein…
Perturbative Nicolai-Map Diagrammatics: Application to Poincaré Supergravity
Ji-Seong Chae, Hun Jang, Junhyeok Lee
We develop a perturbative, diagrammatic framework for constructing Nicolai maps and apply it to four-dimensional Poincaré supergravity expanded around flat Minkowsk…
Constraining Spatial Curvature with Priors from Swampland Conjectures
Simran Arora, Hun Jang, Shinji Mukohyama
We study a string-motivated theoretical prior on the quintessential dark energy model with exponential potential, \( V(ϕ) = V_0 e^{-λϕ} \), allowing for non-zero spatial curvature.…
Traversable wormhole for string, but not for particle
Hun Jang, Minkyoo Kim, Hocheol Lee +1
We propose a Lorentzian wormhole geometry characterized by a closed string massless sector with nontrivial -flux and a scalar dilaton. In the string frame, the dilaton exhibits…
Supermassive gauginos in supergravity inflation with high-scale SUSY breaking
Hun Jang, Massimo Porrati
A model of supergravity inflation we recently proposed can produce slow roll inflation and a realistic spectrum of particles even without F-term supersymmetry breaking. Supersymmet…
Gauge Theory on Fiber Bundle of Hypercomplex Algebras
Hun Jang
I introduce a way of constructing a fiber bundle whose fibers are given by hypercomplex algebras and woven by appropriate structure group, and present that a novel gauge theory can…
A Realization of Slow Roll Inflation and the MSSM in Supergravity Theories with New Fayet-Iliopoulos Terms
Hun Jang, Massimo Porrati
A new supergravity D-term, not associated to gauged R-symmetry, was recently discovered and used to construct new supergravity models. In this paper we use a generalization of the…
Locally Supersymmetric Effective Field Theories of Inflation
Hun Jang
Supergravity, a locally supersymmetric gauge theory, may provide to describe new physics beyond the Standard Model (BSM). In this sense, cosmological applications of supergravity c…
Relaxed Supergravity
Hun Jang
We propose a novel class of supergravity (called ``Relaxed supergravity'') that can enlarge the space of scalar potentials, relaxing the strongly-constrained form o…
Component Actions of Liberated Supergravity and New Fayet-Iliopoulos Terms in Superconformal Tensor Calculus
Hun Jang, Massimo Porrati
We explicitly compute the component action of certain recently discovered new supergravity actions which enlarge the space of scalar potentials allowed by supersy…
Inflation, Gravity Mediated Supersymmetry Breaking, and de Sitter Vacua in Supergravity with a Kähler-Invariant FI Term
Hun Jang, Massimo Porrati
We use a new mechanism for generating a Fayet-Iliopoulos term in supergravity, which is not associated to an R symmetry, to construct a semi-realistic theory of slow-roll inflation…
Constraining Liberated Supergravity
Hun Jang, Massimo Porrati
Fermionic terms in a class of locally supersymmetric theories called "liberated supergravity" are nonrenormalizable interactions proportional to inverse powers of the supersymmetry…
