1D Majorana Goldstinos and partial supersymmetry breaking in quantum wires

Communications Physics, 2022
Majorana modes realised in topological superconductors are expected to be an important feature for quantum information processing applications.

Dynamical Supersymmetry Breaking in Intersecting Brane Models

, 2010
In this paper we study dynamical supersymmetry breaking in absence of gravity with the matter content of the minimal supersymmetric standard model. The hidden sector of the theory is a strongly coupled gauge theory, realized in terms of microscopic ...

SU(7) Unification of SU(3)_C*SU(4)_W* U(1)_{B-L} [PDF]

, 2011
We propose the SUSY SU(7) unification of the SU(3)_C* SU(4)_W* U(1)_{B-L} model. Such unification scenario has rich symmetry breaking chains in a five-dimensional orbifold.

Preheating, Supersymmetry Breaking, and Baryogenesis [PDF]

Physical Review Letters, 1996
Fluctuations of scalar fields produced at the stage of preheating after inflation are so large that they can break supersymmetry much stronger than inflation itself. These fluctuations may lead to symmetry restoration along flat directions of the effective potential even in the theories where the usual high temperature corrections are exponentially ...

de Sitter Excited State in Heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ Theory

Fortschritte der Physik, Volume 73, Issue 12, December 2025.
Abstract A novel duality sequence is devised to study late‐time cosmology in the heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ setup of Horava and Witten with dynamical walls that are moving towards each other. Remarkably, the dimensionally reduced 4‐dimensional theory does not violate NEC and no bouncing or ekpyrotic phase is observed.

Geometry of orientifold vacua and supersymmetry breaking

Journal of High Energy Physics, 2021
Starting from a peculiar orientifold projection proposed long ago by Angelantonj and Cardella, we elaborate on a novel perturbative scenario that involves only D-branes, together with the two types of orientifold planes O ± and anti-orientifold planes O ¯

Axion Models with High-Scale Supersymmetry Breaking

, 2004
Inspired by the possibility of high-scale supersymmetry breaking in the string landscape where the cosmological constant problem and the gauge hierarchy problem can be solved while the strong CP problem is still a challenge for naturalness, we propose a ...

Corrigendum to “On the stability of open-string orbifold models with broken supersymmetry” [Nucl. Phys. B 957 (2020) 115100]

Nuclear Physics B
We consider an open-string realisation of N=2→N=0 spontaneous breaking of supersymmetry in four-dimensional Minkowski spacetime. It is based on type IIB orientifold theory compactified on T2×T4/Z2, with Scherk–Schwarz supersymmetry breaking implemented ...

Heterotic − type I dual pairs, rigid branes and broken SUSY

Nuclear Physics B, 2020
The moduli space of toroidal type I vacua, which are consistent at the non-perturbative level, is composed of independent branches characterized by the number (0, 16 or 32) of rigid branes sitting on top of orientifold planes.
