Partial breaking of extended supersymmetry [PDF]

open access: yesPhysics Letters B, 1984
Abstract In this letter we use nonlinear realizations to examine the breaking of N = 2 extended supersymmetry to N = 1. We derive lagrangians and transformation laws for the generalized N = 2 Akulov-Volkov goldstino field. We analyze the ghost states and show that they may be collected into N = 1 supermultiplets.

Inflation from Supersymmetry Breaking [PDF]

open access: yes, 2018
I discuss the possibility that inflation is driven by supersymmetry breaking, with the superpartner of the goldstino (sgoldstino) playing the role of the inflaton. Imposing an R-symmetry to satisfy the slow-roll conditions, avoiding the so-called η

Coset construction of a D-brane gauge field

open access: yesNuclear Physics B, 2016
D-branes have a world-volume U(1) gauge field A whose field strength F=dA gives rise to a Born–Infeld term in the D-brane action. Supersymmetry and kappa symmetry transformations of A are traditionally inferred by the requirement that the Born–Infeld ...

Enhancement of Dynamical Coupling in Artificial Spin‐Ice Systems by Incorporating Perpendicularly Magnetized Ferromagnetic Matrix

open access: yesSmall Structures, Volume 6, Issue 7, July 2025.
A new type of artificial spin ice (ASI) lattices, i.e., in the ASI system embedded in the perpendicular magnetic anisotropy (PMA) matrix, is proposed. The numerical simulations reveal a strong magnon–magnon coupling between the bulk second‐order mode of the ASI and the fundamental mode of the PMA matrix, supported by a pronounced anticrossing frequency

Supercurrents in extended supersymmetry

open access: yesNuclear Physics B, 1984
Abstract Using the generalization of Noether's theorem to superspace, spinor superfields in extended superspace are derived that satisfy generalized conservation equations. These spinor superfields are superspace moments involving the superconformal parameters of vector indexed supercurrents as in the unextended case. The vector indexed supercurrents

Supersymmetric probes of wrapped M5-brane backgrounds [PDF]

open access: yes, 2006
In this thesis we consider supersymmetric probes in backgrounds sourced by an M5-brane which is wrapped on holomorphic 2-cycles in C(^2) and C(^3), respectively. For the first case, we use M2-brane probes to compute the BPS spectra of the corresponding N

Supersymmetry in quantum mechanics with point interactions [PDF]

open access: yes, 2003
We investigate supersymmetry in one-dimensional quantum mechanics with point interactions. We clarify a class of point interactions compatible with supersymmetry and present N = 2 supersymmetric models on a circle with two point interactions as well as a

Dark Dimension With (Little) Strings Attached

open access: yesFortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Supergraphs extended to broken supersymmetries

open access: yesNuclear Physics B, 1985
Abstract Supergraph techniques are generalized to the case of broken supersymmetry. The modified superpropagators for the O'Raifeartaigh model are obtained: they are used for the superspace renormalization and the derivation of the effective potential.

Effective Lagrangians [PDF]

open access: yes, 2002
I discuss effective field theories of brane-world models where different sectors break different halves of the extended bulk supersymmetry. It is shown how to consistently couple N = 2 supersymmetric matter to N = 1 superfields that lack N = 2 partners ...
