Vacua of ω-deformed SO(8) supergravity
Journal of High Energy Physics, 2022 We perform a detailed analysis of the vacua of ω-deformed SO(8) supergravity in four dimensions. In particular, using Tensorflow-based numerical methods, we track how the equilibria of the theory change when varying the electric-magnetic deformation ...

Supersymmetry breaking and Nambu-Goldstone fermions in an extended Nicolai model [PDF]
, 2016 We study a model of interacting spinless fermions in a one dimensional lattice with supersymmetry (SUSY). The Hamiltonian is given by the anticommutator of two supercharges $Q$ and ${Q}^{\ifmmode\dagger\else\textdagger\fi{}}$, each of which is comprised ...

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 ...

Camouflaged supersymmetry in solutions of extended supergravities [PDF]
Physical Review D, 2012 We establish a relation between certain classes of flux compactifications and certain families of black hole microstate solutions. This connection reveals a rather unexpected result: there exist supersymmetric solutions of N=8 supergravity that live inside many N=2 truncations, but are not supersymmetric inside any of them.

IIB black hole horizons with five-form flux and extended supersymmetry [PDF]
, 2011 We classify under some assumptions the IIB black hole horizons with 5-form flux preserving more than 2 supersymmetries. We find that the spatial horizon sections with non-vanishing flux preserving 4 supersymmetries are locally isometric either to S1 × S3

Extended supersymmetry and the vacuum
Physics Letters B, 1983 Abstract Using light-cone superspace techniques and the adiabatic formalism, we show that the level shift between the bare and the physical vacua is zero order by order in perturbation theory in theories exhibiting extended supersymmetry.

Linearised actions for N $$ \mathcal{N} $$ -extended (higher-spin) superconformal gravity
Journal of High Energy Physics, 2019 The off-shell actions for N $$ \mathcal{N} $$ -extended conformal supergravity theories in three dimensions were formulated in [1, 2] for 1 ≤ N $$ \mathcal{N} $$ ≤ 6 using a universal approach.

Gauged (Super)Conformal Models
Physical Sciences Forum, 2023 Superconformal mechanics describes superparticle dynamics in near-horizon geometries of supersymmetric black holes. We systematically study the minimal compatible set of constraints required for a gauged superconformal symmetry.

Non-uniqueness of the supersymmetric extension of the O(3) σ-model
Journal of High Energy Physics, 2017 We study the supersymmetric extensions of the O(3) σ-model in 1+1 and 2+1 dimensions. We show that it is possible to construct non-equivalent supersymmetric versions of a given model sharing the same bosonic sector and free from higher-derivative terms.

All (4,0): Sigma models with (4,0) off-shell supersymmetry
Journal of High Energy Physics, 2017 Off-shell (4, 0) supermultiplets in 2-dimensions are formulated. These are used to construct sigma models whose target spaces are vector bundles over manifolds that are hyperkähler with torsion.
