Fundamental physics in a complex material 
Ribhu Kaul (University of Kentucky)
The phenomena of magnetism was known to humans of the ancient world. Yet a microscopic understanding of magnetism only began a century ago with the advent of quantum mechanics and statistical physics and specifically with the introduction of the iconic Ising model in 1920. The deceptively simple Ising model has turned out to host remarkably rich phenomena central to many sophisticated ideas of modern theoretical physics including spontaneous symmetry breaking, the renormalization group, duality and conformal field theory. In this talk I will introduce some of these profound ideas and explain how they come together beautifully in the experimental and theoretical study of a synthetic magnetic material, CoNb2O6, and the exciting new frontiers these studies open up.
