Kvantne črne luknje: Hawkingovo srečanje z Ramanujanom

 

Ena izmed najosupljivejših napovedi Einsteinove splošne teorije relativnosti so črne luknje z nenavadnimi kavzalnimi in kvantnimi lastnostmi. Kot je odkril Hawking, črne luknje v okviru kvantne teorije niso zares črne, pač pa počasi sevajo. Razumevanje Hawkingovega sevanja se je izkazalo za zelo plodno pri poskusih poenotenja splošne teorije relativnosti in kvantne mehanike ter pri spoznavanju kvantne strukture prostora-časa. Raziskave kvantnih črnih lukenj v teoriji strun pa so privedle do nepričakovanih povezav z matematičnimi strukturami, ki jih je ustvaril veliki indijski matematik Ramanujan pred stoletjem. V predavanju bom opisal očarljivo zgodovino, fiziko in matematiko kvantnih črnih lukenj.

 

Predavanje bo v angleščini.

Lepo vabljeni!

Quantum black holes: an encounter between Hawking and Ramanujan

 

Black holes are an astonishing prediction of Einstein's general relativity with bizarre causal and quantum properties. Hawking discovered that in quantum theory a black hole is not really black but is slowly emitting radiation. Understanding the implication of Hawking radiation has proved to be a very valuable guide in our search to unify general relativity with quantum mechanics and to learn about the quantum structure of spacetime. Explorations of quantum black holes in string theory have led to unexpected connections with the mathematical structures created by the great Indian mathematician Ramanujan from a century ago. In this lecture I will describe the fascinating history, physics and mathematics of quantum black holes. 

 

Cordially invited!
