Research topic
Mode towers associated with compact dimensions; masses vary inversely with radius in a circle example.
Independent educational guide. Not affiliated with or endorsed by the universities, professors or laboratories described here. This collection reflects the material currently mapped on Socratic Learn.
Research using string theory, geometry, duality, black-hole physics and quantum-gravity consistency to understand which effective theories can arise from quantum gravity and what those constraints might imply for particle physics and cosmology.

Strings, Geometry, and the Swampland
Geometry becomes physics: compactification and moduliExplain how compactification geometry maps into lower-dimensional fields and couplings.
Supports: Kaluza–Klein theory
Strings, Geometry, and the Swampland
The Dark Dimension: can dark energy point to an extra dimension?Explain the conditional argument for a micron-scale Dark Dimension and its KK tower.
Supports: Kaluza–Klein theory
JHEP 02:022 · 2023
M. Montero, C. Vafa, I. Valenzuela
Why this matters: Combines small observed dark energy, conjectural inputs and bounds into a proposed micron-scale dimension; no dimension is detected.
