Extended defects in curved spacetimes [PDF]

, 1999
This Thesis is concerned with three particular aspects of extended cosmic strings and domain walls in cosmology: their dynamics, gravitation and interaction with a black hole. In Chapter 3, we study the dynamics of an abelian-Higgs cosmic string. We find

Revisiting logarithmic correction to five dimensional BPS black hole entropy

Journal of High Energy Physics
We compute logarithmic correction to the entropy of BPS black holes in asymptotically flat five dimensional space-time using finite temperature black hole geometry and find perfect agreement with the microscopic results and macroscopic computations based

Charged AdS black holes in presence of string cloud and Cardy-Verlinde formula

Nuclear Physics B
In this study, charged AdS black holes with a string cloud are taken into consideration. We identify three distinct black hole solutions within a specific temperature range, which subsequently merge into a single black hole beyond this range in the case ...

Size and shape of rotating strings and the correspondence to black holes

Journal of High Energy Physics
In light of the correspondence between black holes and fundamental strings with non-zero spin, we compute the sizes of rotating strings for small, moderate, and large values of the angular momentum and compare them to the sizes of rotating black holes ...

Black Holes in String Theory

, 2019
Black holes are the hydrogen atoms of quantum gravity. For instance solving the information loss paradox will likely require a deep understanding of how the long-sought quantum gravity theory works. In this thesis we explore how black holes are modelled and how the quantum structure emerges in the context of string theory.

Aspects of finite temperature corrections in string theory [PDF]

, 2011
PhDIn this thesis some aspects of temperature corrections in string theory are analyzed: in particular, we study the thermal contributions to the 4 dimensional effective potential arising from string theory compactifications.

Rotating Einstein-Maxwell black holes in odd dimensions

Journal of High Energy Physics
To construct higher-dimensional counterparts of the Kerr-Newman black holes, we consider Einstein’s equations sourced by a vector field and a negative cosmological constant.

Aspects of Holographic Superconductivity [PDF]

, 2012
In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both
