"Spectral functions from the real-time functional renormalization group"

Presented by Philipp Scior, BNL

Thursday, February 18, 2021, 9:00 am — Videoconference / Virtual Event (see link below)

Abstract: We employ the functional renormalization group approach formulated on the Schwinger-Keldysh contour to calculate real-time correlation functions in scalar field theories. We provide a detailed description of the formalism, discuss suitable truncation schemes for real-time calculations as well as the numerical procedure to self-consistently solve the flow equations for the spectral function. Subsequently, we discuss the relations to other perturbative and non-perturbative approaches to calculate spectral functions, and present a detailed comparison and benchmark in d=0+1dimensions.
