T‐Symmetry in String Geometry Theory

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Fuzzy Gravity: Four‐Dimensional Gravity on a Covariant Noncommutative Space and Unification with Internal Interactions

Fortschritte der Physik, Volume 72, Issue 9-10, October 2024.
Abstract In the present work, an extended description of the covariant noncommutative space is presented, which accommodates the Fuzzy Gravity model constructed previously. It is based on the historical lesson that the use of larger algebras containing all generators of the isometry of the continuous one helped in formulating a fuzzy covariant ...

Equivalence of two contour prescriptions in superstring perturbation theory

Journal of High Energy Physics, 2017
Conventional superstring perturbation theory based on the world-sheet approach gives divergent results for the S-matrix whenever the total center of mass energy of the incoming particles exceeds the threshold of production of any final state consistent ...

Dual D-brane actions in nonrelativistic string theory

Journal of High Energy Physics, 2022
We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string theory.

SUPERCONFORMAL GAUGE THEORIES AND NONCRITICAL SUPERSTRINGS [PDF]

International Journal of Modern Physics A, 2004
We consider effective actions for six-dimensional noncritical superstrings. We show that the addition of N units of RR flux and of Nf space–time filling D5-branes produces AdS 5×S1 solutions with curvature comparable to the string scale. These solutions have the right structure to be dual to [Formula: see text] supersymmetric SU (N) gauge theories ...

Gravitoelectric effect in the condensed magnetic sea

IET Quantum Communication, Volume 5, Issue 2, Page 185-195, June 2024.
The Soon Joe generator produced a certain amount of electricity in the dark stationary state. Gravity or gravitational wave can induce the magnetic seas because gravitons captured in the magnetic seas should induce the gravitoelectric effect without the photoelectric effects. As a result, we formulated a new law for magnetism on Earth. Abstract Trapped

Quantum spectral curve for the η-deformed AdS5×S5 superstring

Nuclear Physics B, 2017
The spectral problem for the AdS5×S5 superstring and its dual planar maximally supersymmetric Yang–Mills theory can be efficiently solved through a set of functional equations known as the quantum spectral curve. We discuss how the same concepts apply

The Monster Sporadic Group and a Theory Underlying Superstring Models [PDF]

, 1996
The pattern of duality symmetries acting on the states of compactified superstring models reinforces an earlier suggestion that the Monster sporadic group is a hidden symmetry for superstring models. This in turn points to a supersymmetric theory of self-

Exploring T‐Duality for Self‐Dual Fields

Fortschritte der Physik, Volume 72, Issue 5, May 2024.
Abstract Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions are studied. This formalism is shown to naturally accommodate the T‐duality relation between Type IIA/IIB theories when compactified on a circle without the need for imposing the self‐duality constraint by hand, as is usually done. The study of this
