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
