Cosmological window onto the string axiverse and the supersymmetry breaking scale [PDF]
Physical Review D, 2018 In the simplest picture, the masses of string axions populating the axiverse depend on two parameters: the supersymmetry-breaking scale M-susy and the action S of the string instantons responsible ...

Gauged Supergravities and Spontaneous Supersymmetry Breaking from the Double Copy Construction. [PDF]
Physical Review Letters, 2017 Supergravities with gauged R symmetry and Minkowski vacua allow for spontaneous supersymmetry breaking and, as such, provide a framework for building supergravity models of phenomenological relevance.

Inflation from high-scale supersymmetry breaking [PDF]
Physical Review D, 2017 Supersymmetry breaking close to the scale of grand unification can explain cosmic inflation. As we demonstrate in this paper, this can be achieved in strongly coupled supersymmetric gauge theories, such that the energy scales of inflation and ...

Moduli stabilisation and the statistics of SUSY breaking in the landscape
Journal of High Energy Physics, 2020 The statistics of the supersymmetry breaking scale in the string landscape has been extensively studied in the past finding either a power-law behaviour induced by uniform distributions of F-terms or a logarithmic distribution motivated by dynamical ...

The Nelson-Seiberg Theorem Generalized with Nonpolynomial Superpotentials
Advances in High Energy Physics, 2020 The Nelson-Seiberg theorem relates R-symmetries to F-term supersymmetry breaking and provides a guiding rule for new physics model building beyond the Standard Model.

A note on supersymmetry breaking [PDF]
Physics Letters B, 1997 Using a simple observation based on holomorphy, we argue that any model which spontaneously breaks supersymmetry for some range of a parameter will do so generically for all values of that parameter, modulo some isolated exceptional points. Conversely, a model which preserves supersymmetry for some range of a parameter will also do so everywhere except

A Note on Modular Invariant Species Scale and Potentials
Fortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023 Abstract The species scale provides an upper bound for the ultraviolet cutoff of effective theories of gravity coupled to a number of light particle species. Modular invariant (super‐)potentials provide a simple and computable expression of the species scale as a function of the moduli in toroidal orbifold compactifications of type II and heterotic ...

Supersymmetry breaking in spatially modulated vacua [PDF]
, 2017 We study spontaneous supersymmetry breaking in spatially modulated stable or meta-stable vacua in supersymmetric field theories. Such spatial modulation can be realized in a higher derivative chiral model for which vacuum energies are either positive ...

Supersymmetric Reshaping and Higher‐Dimensional Rearrangement of Photonic Lattices
Laser &Photonics Reviews, Volume 17, Issue 10, October 2023., 2023 Self‐imaging Jx photonic lattices enable perfect transfer of quantum and classical states, yet are challenging to implement at scale. In this paper, supersymmetry is harnessed to construct 2D systems with spectra identical to that of 1D Jx lattices that retain their key imaging and state transfer properties, while requiring dramatically fewer distinct ...

Light higgsino for gauge coupling unification
Physics Letters B, 2017 We explore gauge coupling unification and dark matter in high scale supersymmetry where the scale of supersymmetry breaking is much above the weak scale.
