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 ...

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

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.

Fast and interpretable support vector classification based on the truncated ANOVA decomposition

GAMM-Mitteilungen, Volume 48, Issue 1, March 2025.
Abstract Support vector machines (SVMs) are an important tool for performing classification on scattered data, where one usually has to deal with many data points in high‐dimensional spaces. We propose solving SVMs in primal form using feature maps based on trigonometric functions or wavelets.

Spinorial cohomology and maximally supersymmetric theories

, 2001
Fields in supersymmetric gauge theories may be seen as elements in a spinorial cohomology. We elaborate on this subject, specialising to maximally supersymmetric theories, where the superspace Bianchi identities, after suitable conventional constraints ...

Supersymmetric horizons at the edge of effective field theory

Journal of High Energy Physics
Abstract What if supersymmetry is not something to be hidden, but something to be reached? We introduce the Supersymmetric Horizon Stabilization (SHS): a conceptually unified and analytically controlled framework for embedding metastable de Sitter vacua and trans-Planckian inflation within effective $

Light Nonabelian Monopoles and Generalized r-Vacua in Supersymmetric Gauge Theories

, 2005
We study a class of N=1 supersymmetric U(N) gauge theories and find that there exist vacua in which the low-energy magnetic effective gauge group contains multiple nonabelian factors, \prod_i SU(r_i), supported by light monopoles carrying the associated ...
