Entanglement, Holography, and the Quantum Phases of Matter
Entanglement, Holography, and the Quantum Phases of Matter Electrons in many interesting materials, such as the high temperature superconductors, exhibit low energy states with complex varieties of quantum entanglement. I will describe how the methods of holography, drawn from string theory, have given us a new tool to describe such states, by relating them to theories of gravitation in curved spacetimes with an extra dimension. I will discuss the impact of such ideas on studies of quantum phase transitions, and of novel metals.
