Supersymmetry breaking and Nambu-Goldstone fermions in an extended Nicolai model [PDF]
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 ...

Extended supersymmetry and the vacuum
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.

Partial N $$ \mathcal{N} $$ = 2 supersymmetry breaking and deformed hypermultiplets
We study partial supersymmetry breaking from N $$ \mathcal{N} $$ = 2 to N $$ \mathcal{N} $$ = 1 by adding non-linear terms to the N $$ \mathcal{N} $$ = 2 supersymmetry transformations.

Supersymmetric many-body Euler–Calogero–Moser model
We explicitly construct a supersymmetric so(n) spin-Calogero model with an arbitrary even number N of supersymmetries. It features 12Nn(n+1) rather than Nn fermionic coordinates and a very simple structure of the supercharges and the Hamiltonian.

IIB black hole horizons with five-form flux and extended supersymmetry [PDF]
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

Linearised actions for N $$ \mathcal{N} $$ -extended (higher-spin) superconformal gravity
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.

Non-uniqueness of the supersymmetric extension of the O(3) σ-model
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.

Gauged (Super)Conformal Models
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.

Weak gravity versus scale separation
We give evidence that fully supersymmetric Anti-de Sitter vacua of extended supergravity with a residual gauge group containing an abelian factor cannot be scale separated as a consequence of the weak gravity conjecture. We prove this for N = 2 and N = 8

All (4,0): Sigma models with (4,0) off-shell supersymmetry
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.
