Weak gravity versus scale separation
Journal of High Energy Physics, 2022 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

Nonperturbative unification and extended supersymmetry [PDF]
Physics Letters B, 1989 Abstract We consider the nonperturbative unification scenario proposed by Maiani, Parisi and Petronzio in N =2 supersymmetric extensions of the standard model. Low-energy gauge coupling constants are computed using two-loop renormalization group equations, with a mass spectrum deduced from simple assumptions on the soft terms necessary to break ...

Journal of High Energy Physics, 2023 With the rapid progress of dark matter direct detection experiments, the attractiveness of the popular bino-dominated dark matter in economical supersymmetric theories is fading.

Pure spinor superspace action for D = 6, N = 1 super-Yang-Mills theory
Journal of High Energy Physics, 2018 A Batalin-Vilkovisky action for D = 6, N = 1 super-Yang-Mills theory, including coupling to hypermultiplets, is given. The formalism involves pure spinor superfields.

Communications on Pure and Applied Mathematics, EarlyView.Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

Pauli-Lubanski, supertwistors, and the superspinning particle
Journal of High Energy Physics, 2017 We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics.

Small 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

CONFORMAL INVARIANCE, N-EXTENDED SUPERSYMMETRY AND MASSLESS SPINNING PARTICLES IN ANTI-DE SITTER SPACE [PDF]
, 1995 Starting with a manifestly conformal (O(d, 2) invariant) mechanics model in d space and two time dimensions, we derive the action for a massless spinning particle in d-dimensional anti-de Sitter space.

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

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.
