False vacuum decay of excited states in finite-time instanton calculus
Abstract Extracting information about a system’s metastable ground state energy employing functional methods usually hinges on utilizing the late-time behavior of the Euclidean propagator, practically impeding the possibility of determining decay widths of excited states. We demonstrate that such ob...
