Complex quantum systems exhibit a variety of unconventional phenomena, such as protected quantized edge currents or excitations with non-trivial statistics.
These phenomena are rooted in the complex global entanglement structure
present in those systems, referred to as topological order. In this
talk, I will explain how one can model the physics of such systems based
on their entanglement structure in a way which allows to reconcile a
local description with global entanglement, and to understand the
emergence of global order from local properties. In particular, I will
discuss how the local symmetry structure of the system can give rise to
global topological order, and the way in which this order shows up in
the edge physics and the entanglement properties of the system.
