A central theme of modern condensed matter physics is to understand old and discover new emergent phenomena in quantum materials. These phenomena emerge through the collective behavior of electrons due to their mutual interactions (correlations). In this talk, I will share with you my unique experience as to how discoveries are made, often in a serendipitous manner, in related research. The pseudogap phenomena have been a quarter-century mystery in condensed matter physics. Our search of these phenomena in iridium oxides has led to the discovery of 3D negative electronic compressibility.

"Quantum Entanglement, Strange Metals, and Black Holes" - Entanglement is a counterintuitive feature of quantum mechanics, which implies that a measurement of one particle can instantaneously determines the state of another well-separated particle. Remarkably, quantum entanglement can also happen en masse, and determines observable properties of macroscopic objects. I will present a simple model of many-particle entanglement, which has led to new insights into two very different classes of systems.

Wegner showed that the Ising lattice gauge theory in 2+1 dimensions has a confinement transition between confining and deconfined states. He also argued that this transition is in the universality class of the 3-dimensional Ising ferromagnet. I will begin with a review and update of these results, using the modern perspective of topological order and deconfined criticality. The confinement transition can be defined precisely also in the presence of matter fields, and I will discuss the relevance of such models to the physics of the hole-doped cuprates near optimal doping.
