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

Type IIB orbifolds with D5-branes and their string duals [PDF]

, 2000
We consider Z2, freely acting orbifolds of the type IIB string with 16 parallel D5-branes. When the string is compactified on T2 X T4 and the D5-branes are wrapped on T2, these systems possess N=2 supersymmetry, originating from the spontaneous, partial ...

Double Copy From Tensor Products of Metric BV■‐Algebras

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

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

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.

Revisiting the multi-monopole point of SU(N) N $$ \mathcal{N} $$ = 2 gauge theory in four dimensions

Journal of High Energy Physics, 2021
Motivated by applications to soft supersymmetry breaking, we revisit the expansion of the Seiberg-Witten solution around the multi-monopole point on the Coulomb branch of pure SU(N) N $$ \mathcal{N} $$ = 2 gauge theory in four dimensions. At this point N

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).

Some Relationships Between Dualities in String Theory [PDF]

, 1995
Some relationships between string theories and eleven-dimensional supergravity are discussed and reviewed. We see how some relationships can be derived from others.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Modular forms and SL(2, ℤ)-covariance of type IIB superstring theory

Journal of High Energy Physics, 2019
The local higher-derivative interactions that enter into the low-energy expansion of the effective action of type IIB superstring theory with constant complex modulus generally violate the U(1) R-symmetry of IIB supergravity by q U units.
