Supersymmetric probes of wrapped M5-brane backgrounds [PDF]
, 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

Exact extended supersymmetry on a lattice: Twisted N=2 super-Yang–Mills in two dimensions
, 2006 We propose a lattice action for two-dimensional super-Yang–Mills theory with a twisted N=2 supersymmetry. The extended supersymmetry is fully and exactly realized on the lattice.

Supersymmetry in quantum mechanics with point interactions [PDF]
, 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

Supergraphs extended to broken supersymmetries
Nuclear 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.

Dark Dimension With (Little) Strings Attached
Fortschritte 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

Extended supersymmetry in the space-time R×S3
, 1990 Following recent work on N=1 rigid supersymmetry in the curved space S3, models with extended supersymmetry are examined. Unusual superalgebras with N=2 and N=3 appear.

Behaviors of two supersymmetry breaking scales in N $$ \mathcal{N} $$ = 2 supergravity
Journal of High Energy Physics, 2019 We study the supersymmetry breaking patterns in four-dimensional N $$ \mathcal{N} $$ = 2 gauged supergravity. The model contains multiple (Abelian) vector multiplets and a single hypermultiplet which parametrizes SO(4, 1)/SO(4) coset.

Foundations of Ghost Stability
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

All partial breakings in N=2 $$ \mathcal{N}=2 $$ supergravity with a single hypermultiplet
Journal of High Energy Physics, 2018 We consider partial supersymmetry breaking in N=2 $$ \mathcal{N}=2 $$ supergravity coupled to a single vector and a single hypermultiplet. This breaking pattern is in principle possible if the quaternion-Kähler space of the hypermultiplet admits (at ...

A Note on the Local Observability of Uniform Hypergraphs
Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 1, March 2025.ABSTRACT Hypergraphs generalize graphs in such a way that edges may connect any number of nodes. If all edges are adjacent to the same number of nodes, the hypergraph is called uniform. Thus, a graph is a 2‐uniform hypergraph. Each uniform hypergraph can be identified with an autonomous dynamical state‐space system, whose vector field is composed of ...
