Superunification underwent a major paradigm shift in 1984 when eleven-dimensional supergravity was knocked off its pedestal by ten-dimensional superstrings. This last year has witnessed a new shift of equal proportions: perturbative ten-dimensional superstrings have in their turn been superseded by a new non-perturbative theory called {\it $M$-theory}, which describes supermembranes and superfivebranes, which subsumes all five consistent string theories and whose low energy limit is, ironically…

We study M-theory compactification on ${\mathbb{T}}^{7}/{\mathbb{Z}}_{2}^{3}$ in the presence of a seven-flux, metric fluxes, and KK monopoles. The effective four-dimensional supergravity has seven

### M-theory Calabi-Yau Quantum Mechanics

This thesis explores an exotic class of M-theory compactifications in which the compact manifold is taken to be a Calabi-Yau five-fold. The resulting effective theory is a one-dimensional N=2

### Possible generalization of the superstring action to eleven dimensions

• Mathematics
• 1998
We suggest a $D=11$ super Poincar\'e invariant action for the superstring which has free dynamics in the physical variables sector. Instead of the standard approach based on the searching for an

### Dynamical supersymmetry enhancement of black hole horizons

This thesis is devoted to the study of dynamical symmetry enhancement of black hole horizons in string theory. In particular, we consider supersymmetric horizons in the low energy limit of string

### TASI Lectures on Branes, Black Holes and Anti-de Sitter Space

In the light of the duality between physics in the bulk of anti-de Sitter space and a conformal field theory on the boundary, we review the M2, D3 and M5 branes and how their near-horizon geometry

The main goal of the present work is to analyze the cosmological scenario of the induced gravity theory developed in previous works. Such a theory consists on a Yang–Mills theory in a

We consider extremal black hole attractors [both Bogomol'nyi-Prasad-Sommerfield (BPS) and non-BPS] for $\mathcal{N}=3$ and $\mathcal{N}=5$ supergravity in $d=4$ space-time dimensions. Attractors for

Being self-dual, the instantons provide precisely two gravitino zero modes, thus might induce dynamical supersymmetry breaking and imply that all would-be Peccei-Quinn symmetries that arise in four-dimensional string theories are completely broken around the string compactification scale.
