Circuit complexity in interacting QFTs and RG flows
Abstract We consider circuit complexity in certain interacting scalar quantum field theories, mainly focusing on the ϕ 4 theory. We work out the circuit complexity for evolving from a nearly Gaussian unentangled reference state to the entangled ground state of the theory. Our approach uses Nielsen’s...
