High-Power Supersymmetric Semiconductor Laser with a Narrow Linewidth
Photonics, 2023 We have designed and fabricated a kind of supersymmetric slotted Fabry–Perot semiconductor laser near 1550 nm to achieve a single-mode, high-power, and narrow-linewidth operation.

, 2011 We explore an alternative mechanism for the production of gravitino dark matter whereby relic gravitinos originate from the decays of superpartners which are still in thermal equilibrium, i.e. via freeze-in.

Top-squark searches at the Tevatron in models of low-energy supersymmetry breaking [PDF]
, 2002 We study the production and decays of top squarks (stops) at the Tevatron collider in models of low-energy supersymmetry breaking. We consider the case where the lightest Standard Model (SM) superpartner is a light neutralino that predominantly decays ...

Exact Local Supersymmetry, Absence of Superpartners, and Noncommutative Geometries [PDF]
, 1997 It is pointed out that if we allow for the possibility of a multilayered universe, it is possible to maintain exact supersymmetry and arrange, in principle, for the vanishing of the cosmological constant. Superpartner(s) of a known particle will then be associated with the other layers of such a universe.

The GUT Scale and Superpartner Masses from Anomaly Mediated Supersymmetry Breaking [PDF]
, 2000 We consider models of anomaly-mediated supersymmetry breaking (AMSB) in which the grand unification (GUT) scale is determined by the vacuum expectation value of a chiral superfield.

Comments on nonlinear sigma models coupled to supergravity
Physics Letters B, 2017 N=1, D=4 nonlinear sigma models, parametrized by chiral superfields, usually describe Kählerian geometries, provided that Einstein frame supergravity is used.

UV Shadows in EFTs: Accidental Symmetries, Robustness and No‐Scale Supergravity
Fortschritte der Physik, Volume 68, Issue 10, October 2020., 2020 Abstract We argue that accidental approximate scaling symmetries are robust predictions of weakly coupled string vacua, and show that their interplay with supersymmetry and other (generalised) internal symmetries underlies the ubiquitous appearance of no‐scale supergravities in low‐energy 4D EFTs.

Massive vector multiplet with Dirac-Born-Infeld and new Fayet-Iliopoulos terms in supergravity
Journal of High Energy Physics, 2018 We propose a four-dimensional N = 1 supergravity-based Starobinsky-type inflationary model in terms of a single massive vector multiplet, whose action includes the Dirac-Born-Infeld-type kinetic terms and a generalized (new) Fayet-Iliopoulos-type term ...

The scale of superpartner masses and electroweakino searches at the high-luminosity LHC
Journal of High Energy Physics, 2020 Searches for weakly interacting particles is one of the main goals of the high luminosity LHC run. In this work we study the well motivated cases of electroweakinos with mostly Wino and Bino components.
