Homological classification of 4d N $$ \mathcal{N} $$ = 2 QFT. Rank-1 revisited
Argyres and co-workers started a program to classify all 4d N $$ \mathcal{N} $$ = 2 QFT by classifying Special Geometries with appropriate properties. They completed the program in rank-1. Rank-1 N $$ \mathcal{N} $$ = 2 QFT are equivalently classified by

Topological correlators and surface defects from equivariant cohomology
We find a one-dimensional protected subsector of N $$ \mathcal{N} $$ = 4 matter theories on a general class of three-dimensional manifolds. By means of equivariant localization we identify a dual quantum mechanics computing BPS correlators of the ...

Abstract The string theory landscape may include a multitude of ultraviolet embeddings of the Standard Model, but identifying these has proven difficult due to the enormous number of available string compactifications. Genetic Algorithms (GAs) represent a powerful class of discrete optimisation techniques that can efficiently deal with the immensity of

We calculate the instanton partition function of the four-dimensional N = 2 ⋆ $$ \mathcal{N}={2}^{\star } $$ SU(N) gauge theory in the presence of a generic surface operator, using equivariant localization.

Space time interpretation of S-duality and supersymmetry violations of T-duality [PDF]
The S--duality transformations of the lowest order string effective theory admit a space time interpretation for 4-dim backgrounds with one Killing symmetry. Starting from pure gravity and performing a sequence of intertwined T-S-T duality transformations we obtain new solutions which are always pure gravitational. In this fashion, S-duality induces an

Charting the landscape of supercritical string theory
Special solutions of string theory in supercritical dimensions can interpolate in time between theories with different numbers of spacetime dimensions (via dimension quenching) and different amounts of worldsheet supersymmetry (via c-duality).

On T-Duality and Supersymmetry
The interplay between T-duality and supersymmetry in string theory is explored. It is shown that T-duality is always compatible with supersymmetry and simply changes a local realization to a non-local one and vice versa. Non-local realizations become natural using classical parafermions of the underlying conformal field theory.

On the limitations of non-geometric fluxes to realize dS vacua
In this paper, we perform a systematic and analytical exploration of de Sitter conditions in type IIA compactifications with (non-)geometric fluxes along with the standard NS-NS and RR p-form fluxes.
