Symmetry enhancement and duality walls in 5d gauge theories [PDF]
Journal of High Energy Physics, 2020 Gauge theories in four dimensions can exhibit interesting low energy phenomena, such as infrared enhancements of global symmetry. We explore a class of 4d N $$ \mathcal{N} $$ = 1 gauge theories arising from a construction that is motivated by duality ...

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 ...

T-duality and space-time supersymmetry [PDF]
Nuclear Physics B, 1995 We analyze in detail the possible breaking of spacetime supersymmetry under T-duality transformations. We find that when appropiate world-sheet effects are taken into account apparent puzzles concerning supersymmetry in spacetime are solved. We study T-duality in general heterotic $ $-models analyzing possible anomalies, and we find some modifications

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 ...

Deformation of d = 4, N $$ \mathcal{N} $$ ≥ 5 supergravities breaks nonlinear local supersymmetry
Journal of High Energy Physics, 2023 We study d = 4, N $$ \mathcal{N} $$ ≥ 5 supergravities and their deformation via candidate counterterms, with the purpose to absorb UV divergences. We generalize the earlier studies of deformation and twisted self-duality constraint to the case with ...

Superconformal duality-invariant models and N $$ \mathcal{N} $$ = 4 SYM effective action
Journal of High Energy Physics, 2021 We present N $$ \mathcal{N} $$ = 2 superconformal U(1) duality-invariant models for an Abelian vector multiplet coupled to conformal supergravity. In a Minkowski background, such a nonlinear theory is expected to describe (the planar part of) the low ...

Worldsheet (anti)instanton bound states in type II on T 2
Journal of High Energy Physics, 2020 The 1/8 BPS D 6ℛ4 coupling in type II string theory compactified on T 2 receives contributions from worldsheet instantons and anti-instantons wrapping the T 2, up to genus three in string perturbation theory.

On N $$ \mathcal{N} $$ = 4 supersymmetry enhancements in three dimensions
Journal of High Energy Physics, 2023 We introduce a class of 3d theories consisting of strongly-coupled N $$ \mathcal{N} $$ = 4 systems coupled to N $$ \mathcal{N} $$ = 3 Chern-Simons gauge multiplets, which exhibit N $$ \mathcal{N} $$ = 4 enhancements when a peculiar condition on the Chern-
