This session will explore how the quantum entanglement of many particles plays a central role in many aspects of modern physics. In the Sachdev-Ye-Kitaev model, complex entanglement leads to a quantum state that does not have any particle-like excitations at all. It will describe how such many-particle systems are helping us understand modern quantum materials, such as high temperature superconductors, as well as the quantum mechanics of black holes.
