Supersymmetric AdS$$_2\times \Sigma _2$$ 2×Σ2 solutions from tri-sasakian truncation

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
A class of $$\mathrm{AdS}_2\times \Sigma _2$$ AdS2×Σ2 , with $$\Sigma _2$$ Σ2 being a two-sphere or a hyperbolic space, solutions within four-dimensional $$N=4$$ N=4 gauged supergravity coupled to three-vector multiplets with dyonic gauging is identified.

Novel Free Differential Algebras for Supergravity

open access: yesUniverse, 2023
We develop the theory of Free Integro-Differential Algebras (FIDA) extending the powerful technique of Free Differential Algebras constructed by D. Sullivan. We extend the analysis beyond the superforms to integral- and pseudo-forms used in supergeometry.

Quintessence with two energy scales [PDF]

open access: yes, 2001
We study quintessence models using low energy supergravity inspired from string theory. We consider effective supergravity with two scales m_S, the string scale, and m_PL, the Planck scale and show that quintessence naturally arises from a supersymmetry ...

Consistent 4-form fluxes for maximal supergravity [PDF]

open access: yes, 2015
We derive new ansaetze for the 4-form field strength of D=11 supergravity corresponding to uplifts of four-dimensional maximal gauged supergravity. In particular, the ansaetze directly yield the components of the 4-form field strength in terms of the ...

IIB supergravity revisited [PDF]

open access: yesJournal of High Energy Physics, 2005
We show in the SU(1,1)-covariant formulation that IIB supergravity allows the introduction of a doublet and a quadruplet of ten-form potentials. The Ramond-Ramond ten-form potential which is associated with the SO(32) Type I superstring is in the quadruplet. Our results are consistent with a recently proposed $E_{11}$ symmetry underlying string theory.

Modified Supergravity Phenomenology in Gravitational Waves Era

open access: yesUniverse, 2022
We discuss phenomenological aspects of modified supergravity (MSG) in gravitational wave (GW) physics. MSG naturally provides double inflation and primordial black holes (PBHs) as cold dark matter.

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.
