Question: Who was born more recently, Cumrun Vafa, or Rumi?

Context paragraphs:
Vafa–Witten theorem: In theoretical physics, the Vafa–Witten theorem, named after Cumrun Vafa and Edward Witten, is a theorem that shows that vector-like global symmetries (those that transform as expected under reflections) such as isospin and baryon number in vector-like gauge theories like QCD cannot be spontanteously broken as long as the theta angle is zero.  This theorem can be proved by showing the exponential fall off of the propagator of fermions.

Rumi: Jalāl ad-Dīn Muhammad Rūmī (Persian: جلال‌الدین محمد رومی‎ ‎ ), also known as Jalāl ad-Dīn Muhammad Balkhī (جلال‌الدین محمد بلخى ), Mevlânâ/Mawlānā (مولانا , "our master"), Mevlevî/Mawlawī (مولوی , "my master"), and more popularly simply as Rumi (30 September 1207 – 17 December 1273), was a 13th-century Persian Sunni Muslim poet, jurist, Islamic scholar, theologian, and Sufi mystic.  Rumi's influence transcends national borders and ethnic divisions: Iranians, Tajiks, Turks, Greeks, Pashtuns, other Central Asian Muslims, and the Muslims of South Asia have greatly appreciated his spiritual legacy for the past seven centuries.  His poems have been widely translated into many of the world's languages and transposed into various formats.  Rumi has been described as the "most popular poet" and the "best selling poet" in the United States.

F-theory: F-theory is a branch of string theory developed by Cumrun Vafa.  The new vacua described by F-theory were discovered by Vafa and allowed string theorists to construct new realistic vacua — in the form of F-theory compactified on elliptically fibered Calabi–Yau four-folds.  The letter "F" supposedly stands for "Father".

Gopakumar–Vafa invariant: In theoretical physics Rajesh Gopakumar and Cumrun Vafa introduced new topological invariants, which named Gopakumar–Vafa invariant, that represent the number of BPS states on Calabi–Yau 3-fold, in a series of papers.  (see , and also see , .) 　They lead the following formula generating function for the Gromov–Witten invariant on Calabi–Yau 3-fold "M".

Cumrun Vafa: Cumrun Vafa (Persian: کامران وفا‎ ‎ ] ; born 1960) is an Iranian-American string theorist from Harvard University, which he first joined as a Harvard Junior Fellow.  He is the recipient of the 2008 Dirac Medal and the 2016 Breakthrough Prize in Fundamental Physics.

Topological string theory: In theoretical physics, topological string theory is a version of string theory.  Topological string theory was established and is studied by physicists such as Edward Witten and Cumrun Vafa.
