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

Fortschritte 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

Fortschritte 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.

Holographic Grand Unification [PDF]

, 2006
We present a framework for grand unification in which the grand unified symmetry is broken spontaneously by strong gauge dynamics, and yet the physics at the unification scale is described by (weakly coupled) effective field theory.

End of the world boundaries for chiral quantum gravity theories

Journal of High Energy Physics
We describe the construction of large classes of explicit string theory backgrounds corresponding to 6d and 4d chiral theories with end of the world boundaries, and describe the strong coupling phenomena involved in gapping the chiral (but non-anomalous)

Brane webs and magnetic quivers for SQCD

Journal 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

Food 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 ...

Brane-like States in Superstring Theory and the Dynamics of non-Abelian Gauge Theories

, 1997
We propose a string-theoretic ansatz describing the dynamics of SU(N) Yang-Mills theories in the limit of large N in D=4. The construction uses in a crucial way open-string vertex operators that describe non-perturbative brane dynamics. According to our proposal, various gauge theories are described by string theories with the same action, but with ...

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

Generalized Higher Gauge Theory and M5-brane dynamics. Proceedings: Higher structures in String and M-theory, Tohoku Forum for Creativity, March 7-11 2016

, 2016
We give a review of truncated L$_\infty$ algebras, as used in the study of higher gauge theory. These structures are believed to hold the correct properties to adequately describe gauge theory of extended objects. We discuss how to construct topological higher-gauge-invariant theories and how their solutions relate to multisymplectic geometries.

T‐Symmetry in String Geometry Theory

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...
