Abstract:
Holographic duality posits that certain quantum theories without gravity in d dimensions are equivalent to gravitational theories in d+1 dimensions. This strong/weak duality allows us to explore strongly coupled quantum systems by analysing the properties of higher-dimensional, weakly coupled, and often classical gravitational systems, such as black holes. I will begin by reviewing some of the key insights that holography has provided into condensed matter systems and high-energy physics, including developments in hydrodynamics, strongly coupled plasmas, high-temperature superconductors, strange metals, and the quark-gluon plasma. I will then focus on the holographic predictions related to quantum many-body chaos and their deep connections to black hole physics. In particular, I will highlight a newly discovered, precise relation—known as pole skipping—that connects macroscopic hydrodynamics with microscopic quantum chaos.
