Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

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 ...

Scattering of charged tensor bosons in gauge and superstring theories

, 2009
We calculate the leading-order scattering amplitude of one vector and two tensor gauge bosons in a recently proposed non-Abelian tensor gauge field theory and open superstring theory.

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 ...

Ramond-Ramond Central Charges in the Supersymmetry Algebra of the Superstring [PDF]

, 1997
The free action for the massless sector of the Type II superstring was recently constructed using closed RNS superstring field theory. The supersymmetry transformations of this action are shown to satisfy an N=2 D=10 SUSY algebra with Ramond-Ramond ...

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

Superspace Action for the First Massive States of the Superstring [PDF]

, 1998
Using the manifestly spacetime-supersymmetric version of open superstring field theory, we construct the free action for the first massive states of the open superstring compactified to four dimensions.

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

Type I background fields in terms of type IIB ones

, 2008
We choose such boundary conditions for open IIB superstring theory which preserve N=1 SUSY. The explicite solution of the boundary conditions yields effective theory which is symmetric under world-sheet parity transformation $\Omega:\sigma\to-\sigma$. We

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

Fortschritte 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.
