Bosonic construction of superstring theory and related topics [PDF]
, 2002 This thesis splits into two parts. In the first part we introduce a bosonic construction of the ten-dimensional fermionic theories. This construction relies on a consistent truncation procedure which can produce fermions out of bosons. We illustrate this

Journal of the Royal Anthropological Institute, EarlyView.Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Dyonic Black Holes in String Theory [PDF]
, 1993 An exact solution of the low-energy string theory representing static, spherical symmetric dyonic black hole is found. The solution is labeled by their mass, electric charge, magnetic charge and asymptotic value of the scalar dilaton.

Black holes and solitons in string theory
, 1995 In this review I discuss various aspects of some of the recently constructed black hole and soliton solutions in string theory. I begin with the axionic instanton and related solutions of bosonic and heterotic string theory. The latter ten-dimensional solutions can be compactified to supersymmetric monopole, string and domain wall solutions which break

Black hole attractors and the entropy function in four- and five-dimensional N=2 supergravity [PDF]
, 2007 Extremal black holes in theories of gravity coupled to abelian gauge fields and neutral scalars, such as those arising in the low-energy description of compactifications of string theory on Calabi-Yau manifolds, exhibit the attractor phenomenon: on the ...

Journal of High Energy PhysicsWe construct, for the first time, new static non-extremal five-dimensional black hole solutions (without or with squashed horizons) endowing with four different electric charge parameters in the D = 5, N $$ \mathcal{N} $$ = 2 supergravity coupled to ...

Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Smooth supergravity solutions and string states [PDF]
, 2005 In this thesis we study smooth supergravity solutions and their relation to string theory in two different contexts; quotient spaces and asymptotically flat solitonic solutions.

Evaporation of black holes in string theory [PDF]
, 2023 openThis thesis's project studies how black hole evaporation is captured in string theory by so called Quantum Extremal Islands, extremal surfaces that allows to compute the entanglement entropy of Hawking radiation. This project focus on specific 10d

Microstates of non-extremal black holes: a new hope
Journal of High Energy PhysicsWe provide a new roadmap for constructing microstates of non-extremal black holes in supergravity. First, we review the non-linear sigma model of five-dimensional supergravity governing stationary solutions with a U(1) isometry and present the first ...
