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. Recent research on this system
has brought about a new understanding of
superfluidity and its demise in low-dimensional disordered bosonic systems
