Symmetries on the moduli space of (2,2) superstring vacua
Nuclear Physics B, 1991 Abstract Symmetries of the space of (2,2) string vacua for c = 3, 6, 9 are discussed in the context of orbifoldized Landau-Ginzburg theories. A general method for finding the maximal symmetry groups on the moduli space of untwisted marginal operators is presented, by studying deformations of superpotentials.

InfoMat, Volume 7, Issue 9, September 2025.Ga2O3 photodetectors, particularly those dominated by the photoconductive effect, inevitably face a trade‐off between photoresponsivity and response speed. In this work, bilayer‐structure Ga2O3 films are adopted for solar‐blind photodetectors to alleviate the trade‐off between photoresponsivity and response speed.

Systematic study of the SO(10) symmetry breaking vacua in the matrix model for type IIB superstrings [PDF]
Journal of High Energy Physics, 2011 We study the properties of the space-time that emerges dynamically from the matrix model for type IIB superstrings in ten dimensions. We calculate the free energy and the extent of space-time using the Gaussian expansion method up to the third order.

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Top-quark mass coupling and classification of weakly coupled heterotic superstring vacua [PDF]
The European Physical Journal C, 2014 The quest for the Standard Model among the huge number of string vacua is usually based on a set of phenomenological criteria related to the massless spectrum of string models. In this work we study criteria associated with interactions in the effective low energy theory and in particular with the presence of the coupling that provides mass to the top ...

Band Tailoring Enabled Perovskite Devices for X‐Ray to Near‐Infrared Photodetection
Advanced Science, Volume 12, Issue 9, March 6, 2025.Perovskite‐based photodetectors are improved for wide‐spectrum detection X‐rays to near‐infrared using a type‐II heterojunction with tellurium. This design reduces dark current noise and enhances sensitivity, with a scalable sensor array showing promise for imaging applications.

Flux vacua of the mirror octic
Journal of High Energy PhysicsWe 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

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.

Flux vacua in type IIB compactifications on orbifolds: their finiteness and minimal string coupling
Journal of High Energy PhysicsWe perform a detailed study of (supersymmetric) moduli stabilisation in type IIB toroidal orientifolds with fluxes. We provide strong evidence towards exhaustion of the finite number of inequivalent vacua for a given total 3-form flux charge N flux.

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 ...
