The 5d tangram: brane webs, 7-branes and primitive T-cones
Two highly successful approaches to constructing 5d SCFTs are geometric engineering using M-theory on a Calabi-Yau 3-fold and the use of 5-brane webs suspended from 7-branes in Type IIB string theory.

A string theory realization of special unitary quivers in 3 dimensions
We propose a string theory realization of three-dimensional N $$ \mathcal{N} $$ = 4 quiver gauge theories with special unitary gauge groups. This is most easily understood in type IIA string theory with D4-branes wrapped on holomorphic curves in local K3’

Thick Branes in Horndeski Gravity
We investigate thick brane solutions in the Horndeski gravity. In this setup, we found analytical solutions, applying the first‐order formalism to two scalar fields where the first field comes from the nonminimal scalar‐tensor coupling and the second is due to the matter contribution sector.

Aspects of D-Branes as BPS monopoles [PDF]
We investigate some of the properties of D-brane configurations which behave as BPS monopoles. The two D-brane configurations we will study are the enhançon and D-strings attached to D3-branes.We will start by investigating D3-branes wrapped on a K3 ...

A Study of the Early Cosmic Dynamics in a Multifield Model of Inflation and Curvature Perturbations
In this work, we study the cosmological dynamics of the early universe by employing a small field potential in the context of multifield inflation. By investigating analytically the cosmological observables, such as the number of e‐folds N, potential slow‐roll parameters ϵV, ηV, and spectral index ns which carry significant information, we show that ...

braneworld cosmology and holography [PDF]
This thesis is devoted to studying two important aspects of braneworld physics: their cosmology and their holography. We examine the Einstein equations induced on a general (n - 2)-brane of arbitrary tension, embedded in some n-dimensional bulk.

Quadrality for supersymmetric matrix models
We introduce a new duality for N $$ \mathcal{N} $$ = 1 supersymmetric gauged matrix models. This 0d duality is an order 4 symmetry, namely an equivalence between four different theories, hence we call it Quadrality.

Aspects of supersymmetry in multiple membrane theories
PhDThis thesis consists of two parts. In the rst part we investigate the worldvolume supersymmetry algebra of multiple membrane theories. We begin with a description of M-theory branes and their intersections from the perspective of spacetime and ...
