Generalized geometry of two-dimensional vacua [PDF]
, 2014 We derive the conditions for unbroken supersymmetry for a Mink_2, (2,0) vacuum, arising from Type II supergravity on a compact eight-dimensional manifold M_8.

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, EarlyView.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

Superspaces and supersymmetries [PDF]
Communications in Mathematical Physics, 1981 A theory of graded Banach modules over a Banach-Grassmann algebra is developed and applied to differential geometry of super-manifolds. The explicit structure of superspaces carrying Poincare supersymmetry and extended supersymmetry, including central charges, is described.

Higgs in nilpotent supergravity: Vacuum energy and Festina Lente
Physics Letters B, 2023 In this note we study supergravity models with constrained superfields. We construct a supergravity framework in which all (super)symmetry breaking dynamics happen in vacuum with naturally (or otherwise asymptotically) vanishing energy.

Open-string models with broken supersymmetry
, 2002 I review the salient features of three classes of open-string models with broken supersymmetry. These suffice to exhibit, in relatively simple settings, the two phenomena of ``brane supersymmetry'' and ``brane supersymmetry breaking''. In the first class

Foundations of Ghost Stability
Fortschritte der Physik, EarlyView.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.

Scale Hierarchies in Particle Physics and Cosmology
EPJ Web of Conferences, 2016 We discuss possible connections between several scales in particle physics andcosmology, such the the electroweak, inflation, dark energy and Planck scales.

3D dualities and supersymmetry enhancement from domain walls
Journal of High Energy Physics, 2019 We test recently proposed IR dualities and supersymmetry enhancement by studying the supersymmetry on domain walls. In the SU(3) Wess-Zumino model studied in [1, 2], we show that domain walls exhibit supersymmetry enhancement.
