Comment on "Geometry of the Grosse-Wulkenhaar model"
Dragan Prekrat
We clarify a key point in the geometric reinterpretation of the Grosse$\unicode{x2013}$Wulkenhaar (GW) model proposed in "Geometry of the Grosse-Wulkenhaar model" [JHEP 03 (2010) 0…

Pinpointing Triple Point of Noncommutative Matrix Model with Curvature
Dragan Prekrat, Benedek Bukor, Juraj Tekel
We study a Hermitian matrix model with a quartic potential, modified by a curvature term , where is a fixed external matrix. Inspired by the truncated Heisen…

Detecting scaling in phase transitions on the truncated Heisenberg algebra
Dragan Prekrat, Kristina Neli Todorović-Vasović, Dragana Ranković
We construct and analyze a phase diagram of a self-interacting matrix field coupled to curvature of the non-commutative truncated Heisenberg space. The model reduces to the renorma…
