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
Black holes, topological strings, and exact quantum gravity cluesExplain why controlled black-hole microstate counts test a quantum-gravity framework.
Supports: Black-hole entropy
Phys. Lett. B 379:99–104 · 1996
A. Strominger, C. Vafa
Why this matters: Matches a controlled BPS microstate count to gravitational entropy; this is theoretical evidence in a restricted setting.
DOI: 10.1016/0370-2693(96)00345-0
Phys. Rev. D 70:106007 · 2004
H. Ooguri, A. Strominger, C. Vafa
Why this matters: Proposes the OSV relation for restricted BPS settings, with ensemble and correction subtleties; not a universal identity.
DOI: 10.1103/PhysRevD.70.106007
Bull. Amer. Math. Soc. 62(1); survey, online 2024; pages not verified · 2025
C. Vafa
Why this matters: Connects protected genus-one amplitudes and holomorphic torsion to proposed species-scale and entropy interpretations; the inferred DOI in the source is deliberately omitted.
