Locality and causality properties of light cone string field theory [PDF]

open access: yes, 2004
The recent discovery of a new maximally supersymmetric background for the type IIB superstring theory has revived the interest in light cone string field theory.

End of the world brane networks for infinite distance limits in CY moduli space

open access: yesJournal of High Energy Physics
Dynamical Cobordism provides a powerful method to probe infinite distance limits in moduli/field spaces parameterized by scalars constrained by generic potentials, employing configurations of codimension-1 end of the world (ETW) branes.

Higher-dimensional black holes: Braneworld stars and Hawking radiation. [PDF]

open access: yes, 2007
In this thesis two aspects of braneworld models are studied. A new attempt at finding the metric of a braneworld black hole within the second Randall-Sundrum model is explored. Branes containing distributions of perfect fluid are embedded in a variety of

Morse-Bott inequalities, topology change and cobordisms to nothing

open access: yesJournal of High Energy Physics
The Cobordism Conjecture predicts spacetime-ending configurations, such as Bubbles of Nothing (BoN), being commonplace. These correspond to vacuum decays in which the compactification manifold C n $$ {\mathcal{C}}_n $$ shrinks to a point, with the ...

New comments on six-dimensional orientifold vacua with reduced rank and unitarity constraints

open access: yesJournal of High Energy Physics
We revisit and extend the construction of six-dimensional orientifolds built upon the T 4/ℤ N orbifolds with a non-vanishing Kalb-Ramond background, both in the presence of N $$ \mathcal{N} $$ = (1, 0) supersymmetry and Brane Supersymmetry Breaking, thus

Black holes as probes of moduli space geometry

open access: yesJournal of High Energy Physics, 2023
We argue that supersymmetric BPS states can act as efficient finite energy probes of the moduli space geometry thanks to the attractor mechanism. We focus on 4d N $$ \mathcal{N} $$ = 2 compactifications and capture aspects of the effective field theory ...

Properties of enhançons in supergravity [PDF]

open access: yes, 2003
A certain class of naked singularities, related to N = 2 pure super Yang-Mills theory, are resolved in string theory with the enhançon mechanism. We study the properties of the enhançon in supergravity.

Scale separation from O-planes

open access: yesJournal of High Energy Physics
Orientifold planes play a crucial role in flux compactifications of string theory, and we demonstrate their deep connection to achieving scale-separated solutions.

Supersymmetric scale-separated AdS3 orientifold vacua of type IIB

open access: yesJournal of High Energy Physics
I construct supersymmetric AdS3 vacua of type IIB string theory that exhibit parametric scale separation in the controlled regime. These solutions arise from compactifications on seven-dimensional manifolds equipped with co-closed G 2-structures, in the ...

Bulk fields with brane terms

open access: yes, 2003
In theories with branes, bulk fields get in general divergent corrections localized on these defects. Hence, the corresponding brane terms are renormalized and should be included in the effective theory from the very beginning.
