BFT2: a general class of 2d N $$ \mathcal{N} $$ = (0, 2) theories, 3-manifolds and toric geometry

open access: yesJournal of High Energy Physics, 2022
We introduce and initiate the study of a general class of 2d N $$ \mathcal{N} $$ = (0, 2) quiver gauge theories, defined in terms of certain 2-dimensional CW complexes on oriented 3-manifolds. We refer to this class of theories as BFT2’s.

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

open access: yesFortschritte 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.

Quiver BPS indices from crystal profiles

open access: yesJournal of High Energy Physics
We derive new exact formulae for elliptic genera in two spacetime dimensions with N $$ \mathcal{N} $$ ≥ 2 supercharges, as well as their one- and zero-dimensional counterparts (for Witten indices and matrix-model partition functions).

Bipartite field theories and D-brane instantons

open access: yesJournal of High Energy Physics, 2018
We study D-brane instantons in systems of D3-branes at toric CY 3-fold singularities. The instanton effect can be described as a backreaction modifying the geometry of the mirror configuration, in which the breaking of U(1) symmetries by the instanton ...

Probing the Black Hole Interior with Holographic Entanglement Entropy and the Role of AdS/BCFT Correspondence

open access: yesFortschritte der Physik, Volume 73, Issue 9-10, October 2025.
The present work, entitled: Probing the Black Hole Interior with Holographic Entanglement Entropy and the Role of AdS/BCFT Correspondence by Fabiano F. Santos, is presented as an investigation of the black hole interior using the Holographic Entanglement Entropy (HEE) and AdS/BCFT Correspondence.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Brane webs and magnetic quivers for SQCD

open access: yesJournal of High Energy Physics, 2020
It is widely considered that the classical Higgs branch of 4d N $$ \mathcal{N} $$ = 2 SQCD is a well understood object. However there is no satisfactory understanding of its structure.

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the effects of climate change on the risk of transmission of foodborne pathogens

open access: yesFood Risk Assess Europe, Volume 3, Issue 3, July 2025.
Abstract The Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) has carried out an updated review of the scientific evidence on the influence of climate change on the transmission of foodborne pathogens. This global phenomenon represents an emerging threat to food safety and public health, since alterations in weather ...

Factorized quantum curves and minuscule vertices in 3D duality cascades with FI parameters

open access: yesJournal of High Energy Physics
In the study of duality cascades in three-dimensional gauge theories without FI parameters, an important role is played by a fundamental domain whose vertices correspond to brane configurations with vanishing relative ranks.
