Explicit superstring vacua in a background of gravitational waves and dilaton [PDF]
, 1994 SummaryWe present an explicit solution of superstring effective equations, represented by gravitational waves and dilaton backgrounds. Particular solutions will be examined in a forthcoming note.

Mirror symmetry for G 2-manifolds: twisted connected sums and dual tops
Journal of High Energy Physics, 2017 Recently, at least 50 million of novel examples of compact G 2 holonomy manifolds have been constructed as twisted connected sums of asymptotically cylindrical Calabi-Yau threefolds.

De-Sitter vacua via consistent D terms [PDF]
, 2005 We introduce a new mechanism for producing locally stable de-Sitter or Minkowski vacua, with spontaneously broken N=1 supersymmetry and no massless scalars, applicable to superstring and M-theory compactifications with fluxes. We illustrate the mechanism

Scaling limits of dS vacua and the swampland
Journal of High Energy Physics, 2019 We discuss the properties of massive type IIA flux compactifications. In particular, we investigate in which case one can obtain dS vacua at large volume and small coupling.

New de Sitter solutions of 10d type IIB supergravity
Journal of High Energy Physics, 2020 We find and study 17 new de Sitter solutions of ten-dimensional (10d) type IIB supergravity with intersecting D 5-branes and orientifold O 5-planes, as well as a new Minkowski one.

Systematics of type IIB moduli stabilisation with odd axions
Journal of High Energy Physics, 2022 Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua.

The tadpole conjecture at large complex-structure
Journal of High Energy Physics, 2022 The tadpole conjecture by Bena, Blåbäck, Graña and Lüst effectively states that for string-theory compactifications with a large number of complex-structure moduli, not all of these moduli can be stabilized by fluxes.

Universal Entanglement and an Information‐Complete Quantum Theory
Advanced Physics Research, Volume 5, Issue 4, April 2026.This Perspective summarize an informationcomplete quantum theory which describes a fully quantum world without any classical systems and concepts. Here spacetime/gravity, having to be a physical quantum system, universally entangles matter (matter fermions and their gauge fields) as an indivisible trinity, and encodes information‐complete physical ...
