Analyticity and crossing symmetry of superstring loop amplitudes

Journal of High Energy Physics, 2019
Bros, Epstein and Glaser proved crossing symmetry of the S-matrix of a theory without massless fields by using certain analyticity properties of the off-shell momentum space Green’s function in the complex momentum plane.

Classical spectral curve of the AdS5 × S 5 lambda superstring

Journal of High Energy Physics, 2020
The classical spectral curve for the worldsheet theory of the AdS5 ×S 5 lambda superstring is constructed. The lambda string is interpreted as a regularized, non-abelian T-dual of the AdS5 ×S 5 superstring with respect to the full PSU(2, 2|4) symmetry ...

On the cigar CFT and Schwarzschild horizons

Nuclear Physics B, 2023
Aspects of shock waves and instantly-created folded strings operators in the supersymmetric SL(2)k/U(1) CFT, and their relevance to the near-horizon physics of Schwarzschild black holes in perturbative superstring theory, are presented.

Ontology After Folk Psychology; or, Why Eliminativists Should Be Mental Fictionalists

Analytic Philosophy, EarlyView.
ABSTRACT Mental fictionalism holds that folk psychology should be regarded as a kind of fiction. The present version gives a Lewisian prefix semantics for mentalistic discourse, where roughly, a mentalistic sentence “p” is true iff “p” is deducible from the folk psychological fiction.

A superstring field theory for supergravity

Journal of High Energy Physics, 2017
A covariant closed superstring field theory, equivalent to classical tendimensional Type II supergravity, is presented. The defining conformal field theory is the ambitwistor string worldsheet theory of Mason and Skinner.

The DNA of Calabi–Yau Hypersurfaces

Fortschritte der Physik, Volume 74, Issue 2, February 2026.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Heterotic string field theory with manifest spacetime supersymmetry

Journal of High Energy Physics
Using the hybrid formalism with manifest N = 1 d = 4 spacetime supersymmetry, we construct the quadratic term in the heterotic superstring field theory action.

Superstrings on AdS3 at k = 1

Journal of High Energy Physics, 2018
We study superstring theory in three dimensional Anti-de Sitter spacetime with NS-NS flux, focusing on the case where the radius of curvature is equal to the string length.

Quantum GraviElectro Dynamics

Annalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,
