Deconstructing de Sitter [PDF]

, 2001
Semiclassical gravity predicts that de Sitter space has a finite entropy. We suggest a picture for Euclidean de Sitter space in string theory, and use the AdS/CFT correspondence to argue that de Sitter entropy can be understood as the number of degrees ...

On the central charge of spacetime current algebras and correlators in string theory on AdS3

Journal of High Energy Physics, 2015
Spacetime Virasoro and affine Lie algebras for strings propagating in AdS3 are known to all orders in α′. The central extension of such algebras is a string vertex, whose expectation value can depend on the number of long strings present in the ...

Blaze: A High performance Big Data Computing System for High Energy Physics

Journal of Physics: Conference Series, 2023
High energy physics (HEP) is moving towards extremely high statistical experiments and super-large-scale simulation of theory. In order to handle the challenge of rapid growth of data volumes, distributed computing and storage frameworks in Big Data area

Engineering Holographic Superconductor Phase Diagrams [PDF]

, 2016
We study how to engineer holographic models with features of a high temperature superconductor phase diagram. We introduce a field in the bulk which provides a tunable "doping" parameter in the boundary theory.

Stringy Effects During Inflation and Reheating [PDF]

, 2005
We consider inflationary cosmology in the context of string compactifications with multiple throats. In scenarios where the warping differs significantly between throats, string and Kaluza-Klein physics can generate potentially observable corrections to ...

RG flow and thermodynamics of causal horizons in higher-derivative AdS gravity

Journal of High Energy Physics, 2016
In arXiv:1508.01343 [hep-th], one of the authors proposed that in AdS/CFT the gravity dual of the boundary c-theorem is the second law of thermodynamics satisfied by causal horizons in AdS and this was verified for Einstein gravity in the bulk.

Quantum machine learning in high energy physics [PDF]

Machine Learning: Science and Technology, 2020
Machine learning has been used in high energy physics (HEP) for a long time, primarily at the analysis level with supervised classification. Quantum computing was postulated in the early 1980s as way to perform computations that would not be tractable ...

Explainability of High Energy Physics events classification using SHAP

Journal of Physics: Conference Series, 2023
Complex machine learning models have been fundamental for achieving accurate results regarding events classification in High Energy Physics (HEP). However, these complex models or black-box systems lack transparency and interpretability. In this work, we
