Physics Colloquium: "Messy magnets and dirty superfluids"
Magnets and superfluids provide the simplest examples of symmetry breaking and correlations in interacting quantum systems. When disorder is thrown into the mix, particularly in low-dimensional quantum systems, novel and universal behavior often emerges. In my talk I will first explore some surprising effects of disorder in systems of non-interacting electrons, and magnetic chains. I will then focus on the superfluid-insulator transition for interacting bosons in a disordered environment, where recent research brought about a new understanding of superfluidity and its demise in low-dimensional disordered bosonic systems.
