Motiv<strong>at</strong>ion<br />
• <strong>Entanglement</strong> <strong>entropy</strong> is a clear measure of <strong>quantum</strong> mechanical<br />
correl<strong>at</strong>ions in many body systems and field theories.<br />
• It is however a very non-local quantity which very difficult to measure in<br />
macroscopic <strong>quantum</strong> systems.<br />
• Its behavior near <strong>quantum</strong> <strong>critical</strong> <strong>points</strong> is largely not understood except in<br />
one dimension.<br />
• Recent results show it is a quantity of interest in topological phases.<br />
