DESCRIPTION:Speakers: Claudio Chamon (Purdue University)\n\nWe introduce a
  framework for emulating graphs and\, through them\, curved spaces of arbi
 trary dimension\, using arrays of superconducting wires. By discretizing a
  space into a graph\, assigning a superconducting wire with a rigid phase 
 to each vertex\, and coupling pairs of wires through Josephson junctions a
 long the graph edges\, arbitrary geometries and topologies can be engineer
 ed in a controlled setting. The superconducting phases then realize scalar
  field theories on the emergent geometry. We establish experimentally real
 istic conditions for implementing these architectures and develop a dictio
 nary relating measurable circuit observables to quantities in the emulated
  field theory. As an application\, we develop the implementation of hyperb
 olic (Anti-de Sitter) spaces of constant negative curvature and use them a
 s an experimentally accessible platform to explore holographic duality in 
 arbitrary dimension. We investigate the effects of disorder in the Josephs
 on couplings\, which translate into metric variations in the bulk-boundary
  correspondence\, and analyze their impact on boundary scaling exponents b
 oth analytically and numerically\, finding that holographic duality remain
 s robust even in the presence of strong disorder. Beyond holography\, the 
 framework opens a broad range of architectural possibilities\, including t
 he exploration of physics on highly nontrivial graphs and toy models of dy
 namical spacetimes.\n\nhttps://indico.psi.ch/event/18888/
