QUANTUM SPIN SYSTEMS LIEB-ROBINSON BOUNDS AND DISORDER

Quantum spin systems are considered simple yet important models of interacting many- particle systems. In the past ve years, Lieb-Robinson bounds have been shown to be a
powerful tool to turn the inherent locality of quantum spin systems into useful estimates to study the dynamics as well as properties of ground states.
In this talk, I will discuss Lieb-Robinson bounds and how the presence of disorder aects the speed of information propagation in quantum spin systems.
