Self-duality and supersymmetry
Physics Letters B, 2010 We observe that the Hamiltonian H = D^2, where D is the flat 4d Dirac operator in a self-dual gauge background, is supersymmetric, admitting 4 different real supercharges. A generalization of this model to the motion on a curved conformally flat 4d manifold exists.

Review of Lattice Supersymmetry and Gauge-Gravity Duality [PDF]
International Journal of Modern Physics A, 2015 We review the status of recent investigations on validating the gauge-gravity duality conjecture through numerical simulations of strongly coupled maximally supersymmetric thermal gauge theories.

Duality Covariant Type IIB Supersymmetry and Nonperturbative Consequences [PDF]
Physical Review D, 1997 Type-IIB supersymmetric theories have an SL(2,Z) invariance, known as U-duality, which controls the non-perturbative behavior of the theory. Under SL(2,Z) the supercharges are doublets, implying that the bosonic charges would be singlets or triplets ...

Duality and supersymmetry breaking in string theory [PDF]
Physics Letters B, 1990 Abstract Target-space duality is incorporated in previously proposed effective actions describing non-perturbative supersymmetry breaking in string theory via gaugino condensation. Duality-preserving vacua with broken supersymmetry and fixed unified coupling constant do generically occur.

Transformation of Black-Hole Hair under Duality and Supersymmetry [PDF]
Nuclear Physics B, 1997 We study the transformation under the String Theory duality group of the observable charges (mass, angular momentum, NUT charge, electric, magnetic and different scalar charges) of four dimensional point-like objects whose asymptotic behavior constitutes

Twisted orientifold planes and S-duality without supersymmetry
Journal of High Energy PhysicsWe construct a novel orientifold of type IIB string theory that breaks all supersymmetries. It is a closed string theory without open sector and it can be understood as a Scherk-Schwarz deformation in which supersymmetry is restored at infinite radius ...

Supersymmetry and dualities [PDF]
Nuclear Physics B - Proceedings Supplements, 1996 Duality transformations with respect to rotational isometries relate supersymmetric with non-supersymmetric backgrounds in string theory. We find that non-local world-sheet effects have to be taken into account in order to restore supersymmetry at the string level.

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.

Supersymmetry and gravitational duality [PDF]
Physical Review D, 2009 We study how the supersymmetry algebra copes with gravitational duality. As a playground, we consider a charged Taub-NUT solution of D=4, N=2 supergravity. We find explicitly its Killing spinors, and the projection they obey provides evidence that the dual magnetic momenta necessarily have to appear in the supersymmetry algebra. The existence of such a
