We review applications of string theory to cosmology, from primordial times to the present-
day accelerated expansion. Starting with a brief overview of cosmology and string …

These lecture notes provide a pedagogical introduction, with exercises, to the techniques
used in attempts to construct vacua with stabilized moduli in string theory. The reader is only …

In this review, a number of approaches to superstring cosmology which make use of key
features which distinguish string theory from point particle theories are discussed, with …

A bstract We discuss minimally supersymmetric AdS 3 flux vacua of massive type IIA
supergravity on G2-orientifolds. We find that configurations with broken scale-separation can …

We present minimally supersymmetric AdS $ _4 $ flux vacua derived from massive type IIA
compactified on $ T^ 6/\mathbb {Z} _3\times\mathbb {Z} _3 $ orbifold, characterized by …

Abstract $ Circuit~ Complexity $, a well known computational technique has recently
become the backbone of the physics community to probe the chaotic behaviour and random …

A bstract Glauber-Sudarshan states, sometimes simply referred to as Glauber states, or
alternatively as coherent and squeezed-coherent states, are interesting states in the …

A bstract We attempt a systematic analysis of string-theoretic quintessence models as an
alternative to metastable de Sitter vacua. It appears that, within the boundaries of what is …

A bstract We show that four-dimensional de Sitter space is a Glauber-Sudarshan state, ie a
coherent state, over a supersymmetric solitonic background in full string theory. We argue …

Higher-derivative corrections to cosmological effective actions in string theory are largely
constrained by T-duality, but have been computed hitherto only to the first few orders in the …
