Abstract:
In analogy with the electromagnetic theory, we resolve the Riemann curvature into electric and magnetic parts and consider the analogous duality transformation which keeps the Einstein action for vacuum invariant. It is remarkable that the duality symmetry of the action also leads to the vacuum field equation without cosmological constant. Further invariance of the vacuum equation and the action under the gravito-electric duality require gravitational constant to change sign.

Abstract:
I propose that self-duality in quantum phase-space provides the criteria for the selection of the quantum gravity vacuum. The evidence for this assertion arises from two independent considerations. The first is the phenomenological success of the free fermionic heterotic-string models, which are constructed in the vicinity of the self-dual point under T-duality. The relation between the free fermionic models and the underlying Z2×Z2 toroidal orbifolds is discussed. Recent analysis revealed that the Z2×Z2 free fermionic orbifolds utilize an asymmetric shift in the reduction to three generations

Abstract:
By resolving the gravitational field into electric and magnetic parts, we define an electrogravity duality transformation and discover an interesting property of the field. Under the duality transformation, a vacuum/flat space–time maps into the original space–time with a topological defect of global monopole/texture. The electrogravity-duality is thus a topological defect generating process. It turns out that all black hole solutions possess dual solutions that imbibe a global monopole.

The vanishing of the cosmological constant and the absence of a massless dilaton might be explained by a duality between a supersymmetric string vacuum in three dimensions and a nonsupersymmetric string vacuum in four dimensions.

Abstract:
The decay of the string perturbative vacuum, if triggered by a suitable, duality-breaking dilaton potential, can efficiently proceed via the parametric amplification of the Wheeler–De Witt wave function in superspace, and can appropriately describe the birth of our Universe as a quantum process of pair production from the vacuum.

Abstract:
Quantum field theory (QFT) and general relativity (GR) are pillars of modern physics, each supported by extensive experimental evidence. QFT operates within Lorentzian spacetime, while GR ensures local Lorentzian geometry. Despite their successes, these frameworks diverge significantly in their estimations of vacuum energy density, leading to the cosmological constant problem—a discrepancy where QFT estimates exceed observed values by 123 orders of magnitude. This paper addresses this inconsistency by tracing the cooling evolution of the universe’s gauge symmetries—from SU(3)×SU(2)×U(1) at hig

Abstract:
We show that for a string moving in a background consisting of maximally symmetric gravity, dilaton field and second rank antisymmetric tensor field, the O(d) ⊗ O(d) transformation on the vacuum solutions gives inequivalent solutions that are not maximally symmetric. We then show that the usual physical meaning of maximal symmetry can be made to remain unaltered even if torsion is present and illustrate this through two toy models by determining the torsion fields, the metric and Killing vectors. Finally we show that under the O(d) ⊗ O(d) transformation this generalized maximal symmetry can be

Après une introduction aux notions géométriques nécessaires, cette thèse examine le rôle des flux dans la compactification supersymétrique sous différents angles.

This thesis is devoted to the study of specific solutions in extended supergravity theories. In the first introductory Chapter, we analyze the basic ideas underlying supersymmetry and supergravity models, focusing on the idea of supergravity as a powerful effective low energy approach to more fundamental underlying theories like superstring/M-theory. Subsequently, the thesis is divided into two parts: a first one (consisting in Chapter 2 and 3) in which black hole solutions to ungauged supergravity models are discussed; a second remaining part (Chapter 4 and 5) in which we analyze the constru

Abstract In this chapter, we shall look at various forms of the ASD condition on the curvature of a metric in four dimensions. The conditions are naturally expressed in terms of ‘Lax pairs’ of vector fields, either on space-time itself or on some bundle over it. By interpreting a vector field as a generator of a diffeomorphism group, we can represent some of the conditions as special cases of the ASDYM equations, but with infinite-dimensional gauge groups. In §13.1-4 we derive various forms of the ASD condition and its subcases on the curvature of a metric. In §13.5 we describe the extension o

Abstract:
This article describes the "Dimming effect" that is produced by the Doppler effect applied to a quantity of individual photons arriving to a receiver from a moving source of light. The corpuscular-wave dualism of light suggests that the well-known Doppler effect, which is currently applied only to the wave component of light, should also be considered for the corpuscular component of light. Application of the Doppler effect on a quantity of photons leads to the "Dimming Effect" - as the faster light source is moving away from observer - the dimmer its brightness appears.
