Matrix geometries and Matrix Models
Rodrigo Delgadillo-Blando, Denjoe O'Connor
We study a two parameter single trace 3-matrix model with SO(3) global symmetry. The model has two phases, a fuzzy sphere phase and a matrix phase. Configurations in the matrix pha…
Matrix Models, Gauge Theory and Emergent Geometry
Rodrigo Delgadillo-Blando, Denjoe O'Connor, Badis Ydri
We present, theoretical predictions and Monte Carlo simulations, for a simple three matrix model that exhibits an exotic phase transition. The nature of the transition is very diff…
Geometry in transition: A model of emergent geometry
Rodrigo Delgadillo-Blando, Denjoe O'Connor, Badis Ydri
We study a three matrix model with global SO(3) symmetry containing at most quartic powers of the matrices. We find an exotic line of discontinuous transitions with a jump in the e…
Towards Noncommutative Fuzzy QED
Rodrigo Delgadillo-Blando, Badis Ydri
We study in one-loop perturbation theory noncommutative fuzzy quenched QED_4. We write down the effective action on fuzzy S**2 x S**2 and show the existence of a gauge-invariant UV…
Quantum effective potential for U(1) fields on S^2_L X S^2_L
P. Castro-Villarreal, R. Delgadillo-Blando, Badis Ydri
We compute the one-loop effective potential for noncommutative U(1) gauge fields on S^2_L X S^2_L. We show the existence of a novel phase transition in the model from the 4-dimensi…
A Gauge-Invariant UV-IR Mixing and The Corresponding Phase Transition For U(1) Fields on the Fuzzy Sphere
P. Castro-Villarreal, R. Delgadillo-Blando, Badis Ydri
From a string theory point of view the most natural gauge action on the fuzzy sphere {\bf S}^2_L is the Alekseev-Recknagel-Schomerus action which is a particular combination of the…
