One-point functions of non-SUSY operators at arbitrary genus in a matrix model for type IIA superstrings

open access: yesNuclear Physics B, 2017
In the previous paper, the authors pointed out correspondence between a supersymmetric double-well matrix model and two-dimensional type IIA superstring theory on a Ramond–Ramond background from the viewpoint of symmetry and spectrum.

Octonionic Magical Supergravity, Niemeier Lattices, and Exceptional & Hilbert Modular Forms

open access: yesFortschritte der Physik, Volume 72, Issue 2, February 2024.
Abstract The quantum degeneracies of Bogomolny‐Prasad‐Sommerfield (BPS) black holes of octonionic magical supergravity in five dimensions are studied. Quantum degeneracy is defined purely number theoretically as the number of distinct states in charge space with a given set of invariant labels.

Quantisation of type IIB superstring theory and the matrix model

open access: yesJournal of High Energy Physics
We discuss the path-integral quantisation of perturbative string theory and show equivalence between the Polyakov-type, Schild-type and Nambu-Goto-type formulations of critical type II superstring theory.

Unification of Gravity and Internal Interactions

open access: yesFortschritte der Physik, Volume 72, Issue 1, January 2024.
Abstract In the gauge theoretic approach of gravity, general relativity is described by gauging the symmetry of the tangent manifold in four dimensions. Usually the dimension of the tangent space is considered to be equal to the dimension of the curved manifold. However, the tangent group of a manifold of dimension d is not necessarily SOd$SO_d$.

An Introduction to Pure Spinor Superstring Theory

open access: yes, 2017
In these lecture notes presented at the 2015 Villa de Leyva Summer School, we give an introduction to superstring theory. We begin by studying the particle and superparticle in order to get a better understanding on the superstring side.

A Study of the Early Cosmic Dynamics in a Multifield Model of Inflation and Curvature Perturbations

open access: yesAdvances in Astronomy, Volume 2024, Issue 1, 2024.
In this work, we study the cosmological dynamics of the early universe by employing a small field potential in the context of multifield inflation. By investigating analytically the cosmological observables, such as the number of e‐folds N, potential slow‐roll parameters ϵV, ηV, and spectral index ns which carry significant information, we show that ...

Superstring field theory with open and closed strings

open access: yesJournal of High Energy Physics, 2020
We construct Lorentz invariant and gauge invariant 1PI effective action for closed and open superstrings and demonstrate that it satisfies the classical BV master equation.

Twistors and 2T-physics

open access: yes, 2005
Two-Time physics applies broadly to the formulation of physics and correctly describes the physical world as we know it. Recently it was applied to a 2T re-formulation of the d=4 twistor superstring, which was suggested by Witten as an efficient approach

STATUS OF SUPERSTRING AND M-THEORY [PDF]

open access: yesInternational Journal of Modern Physics A, 2010
The first lecture gives a colloquium-level overview of string theory and M-theory. The second lecture surveys various attempts to construct a viable model of particle physics. A recently proposed approach, based on F-theory, is emphasized.
