TITLE: Simulating hyperbolic space and black holes on a circuit board

ABSTRACT:

Looking for new bathroom tiles? Why don’t you try regular 7-gons this time! Only requirement: You’d need to live in hyperbolic space of constant negative curvature. To see how this would be like, such tilings have been realized in recent breakthrough experiments in circuit quantum electrodynamics and electrical circuits, where particles are tricked into believing that space is hyperbolic. After an elementary introduction to hyperbolic geometry, I will discuss some of the intriguing features of many-particle systems in hyperbolic space, and then present an electrical circuit realization of the holographic duality between anti-de-Sitter space and conformal field theory in a black hole geometry.
