T-duality invariant approaches to string theory [PDF]
PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.

Fine-tuned vs. natural supersymmetry: what does the string landscape predict?
A vast array of (metastable) vacuum solutions arise from string compactifications, each leading to different 4-d laws of physics. The space of these solutions, known as the string landscape, allows for an environmental solution to the cosmological ...

Radiative natural supersymmetry emergent from the string landscape
In string theory with flux compactifications, anthropic selection for structure formation from a discretuum of vacuum energy values provides at present our only understanding of the tiny yet positive value of the cosmological constant.

Counting string theory standard models
We derive an approximate analytic relation between the number of consistent heterotic Calabi-Yau compactifications of string theory with the exact charged matter content of the standard model of particle physics and the topological data of the internal ...

Modified models of a free boson string and their solutions
In this paper we consider the modified models of a free boson string and examine their dynamics. Modified models of the boson string are investigated from the point of view of the second order formalism (the Polyakov action).

Supergravity solution-generating techniques and canonical transformations of σ-models from O(D, D)
Within the framework of the flux formulation of Double Field Theory (DFT) we employ a generalised Scherk-Schwarz ansatz and discuss the classification of the twists that in the presence of the strong constraint give rise to constant generalised fluxes ...

On a ‘Replicating Character String’ Model [PDF]
In Chaudhuri and Dasgupta's 2006 paper a certain stochastic model for ‘replicating character strings’ (such as in DNA sequences) was studied. In their model, a random ‘input’ sequence was subjected to random mutations, insertions, and deletions, resulting in a random ‘output’ sequence.

Aspects of finite temperature corrections in string theory [PDF]
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.
