Description
In this talk, I will examine the direct connection between entanglement entropy and the notion of irreversibility in the renormalization-group flow in the context of a simple free massive scalar theory. The change of the entanglement entropy for a spherical entangling surface as its radius grows from zero to infinity corresponds to the flow from the UV to the IR. I will provide details regarding the numerical and analytical computation of the entanglement entropy using correlation functions in order to deduce a c-function in 1 + 1 dimensions and an a-function in 3 + 1 dimensions. I will show that both these functions are monotonic and vary continuously between one and zero, as expected for this simple theory.
