Information Spreading in Diffusion Models from Effective Field Theory
Navonil Neogi, Nabil Iqbal
We study score-matching diffusion models with a convolutional architecture. We argue that the inductive bias of locality means that the machinery of effective field theory from phy…
Wilson lines with endpoints in 3d CFT
Nabil Iqbal, Navonil Neogi
In Abelian gauge theories with dynamical matter, Wilson lines can end on the insertions of charged fields. We study the endpoints of Wilson lines in large bosonic QED. at i…
Spontaneous symmetry breaking and Goldstone modes for deep information propagation
Nabil Iqbal, T. Anderson Keller, Yue Song +2
In physical systems, whenever a continuous symmetry is spontaneously broken, the system possesses excitations called Goldstone modes, which allow coherent information propagation o…
AdS-GNN -- a Conformally Equivariant Graph Neural Network
Maksim Zhdanov, Nabil Iqbal, Erik Bekkers +1
Conformal symmetries, i.e.\ coordinate transformations that preserve angles, play a key role in many fields, including physics, mathematics, computer vision and (geometric) machine…
Jena lectures on generalized global symmetries: principles and applications
Nabil Iqbal
This is an elementary set of lectures on generalized global symmetries originally given at the Jena TPI School on QFT and Holography, designed to be accessible to the reader with a…
