The Emergent Fundamental – Exotic Collective Phenomena in Correlated Materials

In the quest to understand our universe, complex materials comprising billions of interacting electrons provide new insight akin to probing alternative universes. Where elementary excitations are considered the fundamental fabric of our universe, we find exotic phenomena defined by novel collective excitations to emerge in correlated electron systems, offering a glimpse of the new fundamental. I will discuss experimental tools by which we can discover and understand such unconventional phases of matter, in particular by fine-tuning materials universes under extreme conditions such as applied pressure and high applied magnetic fields. I will explore examples from my work on materials families such as copper oxide high temperature superconductors, and dual metal-insulating rare earth systems, which display strikingly unusual emergent physical properties requiring new paradigms of understanding.
