Matrix Models, Emergent Gravity, and Gauge Theory
Harold Steinacker
Matrix models of Yang-Mills type induce an effective gravity theory on 4-dimensional branes, which are considered as models for dynamical space-time. We review recent progress in t…
Modelling a Particle Detector in Field Theory
Fabio Costa, Federico Piazza
Particle detector models allow to give an operational definition to the particle content of a given quantum state of a field theory. The commonly adopted Unruh-DeWitt type of detec…
Translation-invariant models for non-commutative gauge fields
Daniel N. Blaschke, Francois Gieres, Erwin Kronberger +2
Motivated by the recent construction of a translation-invariant renormalizable non-commutative model for a scalar field (see arXiv:0802.0791 [math-ph]), we introduce models for non…
Emergent Gravity, Matrix Models and UV/IR Mixing
Harald Grosse, Harold Steinacker, Michael Wohlgenannt
We verify explicitly that UV/IR mixing for noncommutative gauge theory can be understood in terms of an induced gravity action, as predicted by the identification [1] of gravity wi…
Emergent 4D Gravity from Matrix Models
Harold Steinacker
Recent progress in the understanding of gravity on noncommutative spaces is discussed. A gravity theory naturally emerges from matrix models of noncommutative gauge theory. The eff…
Nonlinear Brownian Motion and Higgs Mechanism
Alexander Gluck, Helmuth Huffel
An extension of the stochastic quantization scheme is proposed by adding nonlinear terms to the field equations. Our modification is motivated by the recently established theory of…
