Flux vacua and branes of the minimal superstring [PDF]
, 2004 We analyze exactly the simplest minimal superstring theory, using its dual matrix model. Its target space is one dimensional (the Liouville direction), and the background fields include a linear dilaton, a possible tachyon condensate, and RR flux.

Fortschritte der Physik, Volume 73, Issue 9-10, October 2025.Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

The gravitational sector of 2d (0, 2) F-theory vacua
Journal of High Energy Physics, 2017 F-theory compactifications on Calabi-Yau fivefolds give rise to two-dimensional N = (0, 2) supersymmetric field theories coupled to gravity. We explore the dilaton supergravity defined by the moduli sector of such compactifications.

Stability of vacua and domain walls in supergravity and superstring theory [PDF]
, 1992 We address the possibility of false vacuum decay in N=1 supergravity theories, including those corresponding to superstring vacua. By establishing a Bogomol’nyi bound for the energy density stored in the domain wall of the O(4) invariant bubble, we show ...

Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

De Sitter vacua in no-scale supergravity
Journal of High Energy Physics, 2018 No-scale supergravity is the appropriate general framework for low-energy effective field theories derived from string theory. The simplest no-scale Kähler potential with a single chiral field corresponds to a compactification to flat Minkowski space ...

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.

A universal tachyon in nearly no-scale de Sitter compactifications
Journal of High Energy Physics, 2018 We investigate de Sitter solutions of N=1 $$ \mathcal{N}=1 $$ supergravity with an F-term scalar potential near a no-scale Minkowski point, as they may in particular arise from flux compactifications in string theory.

Analytics of type IIB flux vacua and their mass spectra
Journal of High Energy Physics, 2023 We analyze the tree-level potential of type IIB flux compactifications in warped Calabi-Yau orientifolds, in regions of weak coupling and moderately large complex structure.

Search for NS 3-form Flux Induced Vacua for the Critical Non-Abelian Vortex String [PDF]
International Journal of Modern Physics AIt has been demonstrated that the non-Abelian solitonic vortex string in four-dimensional (4D) $\mathcal{N}=2$ supersymmetric QCD (SQCD) with gauge group U(2) and $N_f=4$ quark hypermultiplets behaves as a critical superstring.
