Topology change and heterotic flux vacua

Journal of High Energy Physics
We investigate the interrelation between topology and Narain T-duality of heterotic flux vacua. We present evidence that all 5 and 4-dimensional Minkowski space heterotic flux backgrounds with 8 supercharges have a locus in the moduli space with a T-dual

Reflection groups and 3d N $$ \mathcal{N} $$ > 6 SCFTs

Journal of High Energy Physics, 2019
We point out that the moduli spaces of all known 3d N $$ \mathcal{N} $$ = 8 and N $$ \mathcal{N} $$ = 6 SCFTs, after suitable gaugings of finite symmetry groups, have the form ℂ 4r /Γ where Γ is a real or complex reflection group depending on whether the

Supersymmetry constraints on U-duality invariant deformations of N $$ \mathcal{N} $$ ≥ 5 supergravity

Journal of High Energy Physics, 2019
Candidate counterterms break E7 type U-duality symmetry of N $$ \mathcal{N} $$ ≥ 5 supergravity theories in four dimensions [1, 2]. A proposal was made in [3] to restore it, starting with a double set of vector fields and argued that a supersymmetric ...

Transcendentality violation in type IIB string amplitudes

Journal of High Energy Physics, 2020
We analyze transcendentality for certain terms that arise in multiloop amplitudes in the low momentum expansion of the four graviton amplitude in type IIB string theory in ten dimensions, based on the constraints of supersymmetry and S-duality.

Exploring the geometry of supersymmetric double field theory

Journal of High Energy Physics, 2022
The geometry of N $$ \mathcal{N} $$ = 1 supersymmetric double field theory is revisited in superspace. In order to maintain the constraints on the torsion tensor, the local tangent space group of O(D) × O(D) must be expanded to include a tower of higher ...

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 ...

Multi-centered N = 2 $$ \mathcal{N}=2 $$ BPS black holes: a double copy description

Journal of High Energy Physics, 2017
We present the on-shell double copy dictionary for linearised N = 2 $$ \mathcal{N}=2 $$ supergravity coupled to an arbitrary number of vector multiplets in four dimensions.

Intersecting surface defects and 3d superconformal indices

Journal of High Energy Physics, 2021
We compute the 3d N $$ \mathcal{N} $$ = 2 superconformal indices for 3d/1d coupled systems, which arise as the worldvolume theories of intersecting surface defects engineered by Higgsing 5d N $$ \mathcal{N} $$ = 1 gauge theories. We generalize some known

String effects and field theory puzzles with supersymmetry [PDF]

, 1996
We investigate field theory puzzles occuring in the interplay between supersymmetry and duality in the presense of rotational isometries (also known as non-triholomorphic in hyper-Kahler geometry).

Non-perturbative string connections [PDF]

, 2000
We discuss the duality between two type I compactifications to four dimensions and an heterotic construction with spontaneous breaking of the N=4 supersymmetry to N=2.
