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 ...

Yukawa Couplings in Heterotic Standard Models [PDF]

, 2006
In this paper, we present a formalism for computing the Yukawa couplings in heterotic standard models. This is accomplished by calculating the relevant triple products of cohomology groups, leading to terms proportional to Q*H*u, Q*Hbar*d, L*H*nu and L ...

dS vacua and the swampland

Journal of High Energy Physics, 2019
In this note we revisit some of the recent 10d and 4d arguments suggesting that the uplifting of supersymmetric AdS vacua leads to a flattening of the potential, preventing the formation of dS vacua.

On scale separation in type II AdS flux vacua

Journal of High Energy Physics, 2020
We study the separation of AdS and Kaluza-Klein (KK) scales in type II 4d AdS orientifold vacua. We first address this problem in toroidal/orbifold type IIA vacua with metric fluxes, corresponding to compactifications in twisted tori, both from the 4d ...

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

De Sitter vacua — when are ‘subleading corrections’ really subleading?

Journal of High Energy Physics, 2023
We consider various string-loop, warping and curvature corrections that are expected to appear in type IIB moduli stabilisation scenarios. It has recently been argued, in the context of strongly-warped LVS de Sitter vacua, that it is impossible to ...

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.

String Vacua with N=2 Supersymmetry in Four Dimensions [PDF]

, 1998
In this article we review four-dimensional string vacua with N=2 space-time supersymmetry. In particular, we will discuss several aspects of the string-string duality between the heterotic string, compactified on $K3\times T^2$, and the type II ...

Flux vacua of the mirror octic

Journal of High Energy Physics
We determine all flux vacua with flux numbers N flux ≤ 10 for a type IIB orientifold-compactification on the mirror-octic three-fold. To achieve this, we develop and apply techniques for performing a complete scan of flux vacua for the whole moduli space

On fluxes in the 19 Landau-Ginzburg model

Journal of High Energy Physics, 2023
In this paper we present a large class of flux backgrounds and solve the shortest vector problem in type IIB string theory on an orientifold of the 19 Landau-Ginzburg model.
