 New Observations about Quantum Field Theory

Zohar Komargodski, The Weizmann Institute

We review recent progress on three thorny and fundamental questions in Quantum Field Theory: The symmetries of second order phase transitions, monotonicity of the renormalization group flow, and the entanglement entropy of the vacuum. We give examples of various applications for theories ranging from boiling water to Quantum Chromodynamics.
