Supersymmetry, T-duality and heterotic α′-corrections [PDF]
Journal of High Energy Physics, 2021 Higher-derivative interactions and transformation rules of the fields in the effective field theories of the massless string states are strongly constrained by space-time symmetries and dualities. Here we use an exact formulation of ten dimensional N $$ \

Non-Abelian duality, parafermions, and supersymmetry [PDF]
Physical Review D, 1996 Non-Abelian duality in relation to supersymmetry is examined. When the action of the isometry group on the complex structures is nontrivial, extended supersymmetry is realized nonlocally after duality, using path-ordered Wilson lines.

T-duality and world-sheet supersymmetry [PDF]
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1995 Four-dimensional string backgrounds with local realizations of N = 4 world-sheet supersymmetry have, in the presence of a rotational Killing symmetry, only one complex structure which is an SO(2) singlet, while the other two form an SO(2) doublet ...

T-duality and space-time supersymmetry [PDF]
Nuclear Physics B, 1995 We analyze in detail the possible breaking of space-time supersymmetry under T-duality transformations. We find that when appropriate world-sheet effects are taken into account apparent puzzles concerning supersymmetry in space-time are solved.

N $$ \mathcal{N} $$ = 2 supersymmetry deformations, electromagnetic duality and Dirac-Born-Infeld actions [PDF]
Journal of High Energy Physics, 2019 We study the general deformation of N $$ \mathcal{N} $$ = 2 supersymmetry transformations of a vector multiplet that forms a (constant) triplet under the SU(2) R-symmetry corresponding to the magnetic dual of the triplet of the Fayet-Iliopoulos (FI ...

Duality and supersymmetry constraints on the weak gravity conjecture [PDF]
Journal of High Energy Physics, 2020 Positivity bounds coming from consistency of UV scattering amplitudes are not always sufficient to prove the weak gravity conjecture for theories beyond Einstein-Maxwell.

Top down approach to topological duality defects [PDF]
Physical Review D, 2022 Topological duality defects arise as codimension one generalized symmetry operators in quantum field theories (QFTs) with a duality symmetry. Recent investigations have shown that in the case of 4D $\mathcal{N} = 4$ Super Yang-Mills (SYM) theory, an ...

Perturbative higher-derivative terms in N $$ \mathcal{N} $$ = 6 asymmetric orbifolds
Journal of High Energy Physics, 2022 We analyse the perturbative four-point amplitudes in the simplest string theory examples of T-fold backgrounds, which enjoy N $$ \mathcal{N} $$ = 6 supersymmetries in four dimensions.

Constraining Spacetime Dimensions in Quantum Gravity by Scale Invariance and Electric-Magnetic Duality [PDF]
Progress of Theoretical and Experimental Physics, 2023 We consider a low energy effective theory of p-branes in a D-dimensional spacetime, and impose two conditions: 1) the theory is scale invariant, and 2) the electric-magnetic dual (D − p − 4)-branes exist and they obey the same type of interactions to ...
