$$dS_5$$ dS5 vacua from matter-coupled 5D $$N=4$$ N=4 gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We study $$dS_5$$ dS5 vacua within matter-coupled $$N=4$$ N=4 gauged supergravity in five dimensions using the embedding tensor formalism. With a simple ansatz for solving the extremization and positivity of the scalar potential, we derive a set of ...

Enhanced Separation Behavior of Metals from Simulated Printed Circuit Boards by Supergravity

open access: yesMetals, 2022
Printed circuit boards (PCBs) contain valuable metals, epoxy resin, and glass fiber, resulting in them being considered as attractive secondary sources of metals.

On N = 2 Truncations of IIB on T^{1,1} [PDF]

open access: yes, 2012
We study the N=4 gauged supergravity theory which arises from the consistent truncation of IIB supergravity on the coset T^{1,1}. We analyze three N=2 subsectors and in particular we clarify the relationship between true superpotentials for gauged ...

T‐Symmetry in String Geometry Theory

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Line and surface defects in 5D $$N=2$$ N = 2 SCFT from matter-coupled F(4) gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields
We study supersymmetric solutions of matter-coupled F(4) gauged supergravity in the forms of $$AdS_2\times S^3$$ A d S 2 × S 3 - and $$AdS_3\times S^2$$ A d S 3 × S 2 -sliced domain walls with a non-vanishing two-form field from the supergravity ...

Spacetime Topology and the Laws of Black Hole-Soliton Mechanics

open access: yesEntropy, 2017
The domain of outer communication of an asymptotically flat spactime must be simply connected. In five dimensions, this still allows for the possibility of an arbitrary number of 2-cycles supported by magnetic flux carried by Maxwell fields. As a result,

On Calabi‐Yau Manifolds at Strong Topological String Coupling

open access: yesFortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract It was recently shown that integrating out M2 states on Calabi‐Yau manifolds captures non‐perturbative topological string physics in the free energy. In this note, It has been shown that the resulting expression manifests a certain duality symmetry: the free energy at strong string coupling is equal to the Calabi‐Yau period at weak string ...

Quantum No-Scale Regimes and String Moduli

open access: yesUniverse, 2018
We review that in no-scale models in perturbative string theory, flat, homogeneous and isotropic cosmological evolutions found at the quantum level can enter into “quantum no-scale regimes„ (QNSRs).

Gauge field corrections to 11-dimensional supergravity via dimensional reduction

open access: yes, 2018
Using the fact that eleven-dimensional supergravity yields type IIA supergravity under dimensional reduction on a circle, we determine higher-derivative terms of 11-dimensional supergravity including the $ R^4 $, $ ({\partial {F_4}})^2 R^2 $ and ...

BPS Geometries and AdS Bubbles [PDF]

open access: yes, 2004
Recently, 1/2-BPS AdS bubble solutions have been obtained by Lin, Lunin and Maldacena, which correspond to Fermi droplets in phase space in the dual CFT picture.
