[hep-th] Семинар групе за гравитацију, честице и поља, петак, 20. децембар 2024.

[prlina]

Poštovane kolege,

najavljujem da će u petak, 20. децембра, Bojana Brkić (Fizički fakultet 
Univerziteta u Beogradu) održati seminar na Institutu za fiziku.

Naslov: Scalar field on fuzzy de Sitter space

Apstrakt: We study a scalar field on a noncommutative model of 
spacetime, the fuzzy de Sitter space, which is based on the algebra of 
the de Sitter group SO(1, d) and its unitary irreducible 
representations. We solve the Klein-Gordon equation in d = 2, 4 and 
show, using a specific choice of coordinates and operator ordering, that 
all commutative field modes can be promoted to solutions of the fuzzy 
Klein-Gordon equation. After that, we discuss the completeness of this 
set of modes.

Seminar počinje u 11:15 uživo na Institutu za fiziku u sali 360 na 2. 
spratu. Osim toga, seminar se može pratiti i preko linka
