Title: The New Dimensions of Quantum Matter
Speaker: Dr. William Witczak-Krempa
Institute: Harvard University
Location: ABB 102
The past decade has seen an outburst of experiments revealing unusual quantum phenomena in diverse systems such as high-temperature superconductors, graphene, and ultra-cold atomic gases. Iâ??ll describe the corresponding novel states of quantum matter that were found, particularly focusing on the striking physics emerging near quantum phase transitions.These are driven by quantum fluctuations, in contrast to the more familiar ones where thermal effects dominate, and lead to intricate quantum fluids. Iâ??ll present recent findings regarding their universal dynamical and quantum entanglement properties. My interdisciplinary approach combines methods from condensed matter with insights from high energy, quantum information and even from the holographic principle of string theory, where an extra dimension becomes useful!
