[hep-th] Seminar grupe za gravitaciju, cestice i polja, 4. februar 2022

[Marija Dimitrijevic Ciric]

Zdravo svima,

evo najave seminara, koji ce u petak 4. februara 2022. drzati Dragan 
Prekrat (Fizicki fakultet, Univerzitet u Beogradu)

Naslov: Phase transitions in matrix models on the truncated Heisenberg 
space

Asptrakt: The important generic problem with QFTs on noncommutative 
spaces is the UV/IR mixing of divergences which interferes with their 
renormalization. The Grosse-Wulkenhaar model solved this problem by 
introducing a harmonic oscillator term that can be interpreted as a 
coupling between the curvature and the field. In this talk, we will 
examine the success of this model from the phase transition point of 
view. We will show that renormalizable and nonrenormalizable versions of 
the 2D noncommutative phi4 model have different phase diagrams.
We will also consider the implications of the striped-phase shifting on 
the renormalization properties of other models.
