From linear to non-linear SUSY and back again
Journal of High Energy Physics, 2017 We show that couplings of the goldstino field, appearing when global supersymmetry is broken, can always be described in superspace by means of a nilpotent chiral superfield X, satisfying X 2 = 0.

Black hole attractors and the entropy function in four- and five-dimensional N=2 supergravity [PDF]
, 2007 Extremal black holes in theories of gravity coupled to abelian gauge fields and neutral scalars, such as those arising in the low-energy description of compactifications of string theory on Calabi-Yau manifolds, exhibit the attractor phenomenon: on the ...

Programmable photonic unitary circuits for light computing
Nanophotonics, Volume 14, Issue 10, Page 1429-1449, May 2025.Abstract Unitarity serves as a fundamental concept for characterizing linear and conservative wave phenomena in both classical and quantum systems. Developing platforms that perform unitary operations on light waves in a universal and programmable manner enables the emulation of complex light–matter interactions and the execution of general‐purpose ...

Locally Supersymmetric Effective Field Theories of Inflation
, 2022 Supergravity, a locally supersymmetric gauge theory, may provide to describe new physics beyond the Standard Model (BSM). In this sense, cosmological applications of supergravity can be the arena for probing outcomes of supergravity. It is also attractive that supergravity can appear as a low-energy effective theory of superstrings, a possible ...

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

Gauge Mediated Supersymmetry Breaking in Five Dimensions
, 2011 PhDIn this thesis we focus on the construction of models in which a supersymmetry breaking hidden sector is located on one fixed point of an extra dimensional interval and the effects are gauge mediated across this interval to the other fixed point ...

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Sneutrino Dark Matter in the BLSSM
Journal of High Energy Physics, 2018 In the framework of the (B − L) Supersymmetric Standard Model (BLSSM), we assess the ability of ground and space based experiments to establish the nature of its prevalent Dark Matter (DM) candidate, the sneutrino, which could either be CP-even or -odd ...

Three-forms and Fayet-Iliopoulos terms in supergravity: scanning Planck mass and BPS domain walls
Journal of High Energy Physics, 2020 We embed a new three-form vector multiplet in N $$ \mathcal{N} $$ = 1 supergravity and we show that it can be used to generate dynamically the Hilbert-Einstein term.

Higher derivative terms and their influence on N=2 supersymmetric systems [PDF]
, 1999 This thesis is concerned with so-called higher derivative terms which arise in low energy approximations to certain physical models. In particular, the aim is to investigate the role that such terms play in low energy N=2 supersymmetric gauge theories in
